This cross-curricular lesson is one of two “lessons we love” from Discover Dairy. Students watch a short video, read a passage on selective breeding in dairy cows, have a discussion and complete a lab exercise in selective breeding.

Lesson

NOTE: While we create most lessons on the Growing Math site ourselves, we do include links to other lessons that are exemplary in their cross-curricular, standards-based design. This is one of two lessons we love from Discover Dairy. The entire 14-page lesson can be downloaded here, including reading passages, lab assignments and answer keys.

You can also go to the Discover Dairy site, which requires a free registration and login to download individual parts of the lesson and see the other lessons they have available.

Start with a video

Watch a four-minute video on dairy farms to kick the lesson off.

Read a passage on selective breeding in dairy cows

You’ll find this on page 13 of the handout linked above or download both reading assignments here (it’s only two pages) or copy the link to assign in your Google classroom to read on line.

Class Discussion on Selective Breeding

See page 2 of the full lesson linked above for suggested discussion questions. Note that the first question asks about the 7 types of dairy cows- the 7 types of cows are picture on the complete lesson plan on page 7.

Lab Exercise #1 : Selective Breeding

Pass out the lab activity #1 sheets, in pages 9 and 10 of the complete lesson plan. You can link directly to those here, if you want to assign in Google classroom or other management system. Note that link includes both labs 1 and 2.

Once students have the materials, explain the lab activity. You may want to use the explanation given on pages 2-3 of the lesson plan.

Answer keys for both lab exercises can be found here.

⏰LESSON TIME

25 -30 minutes including game play

📲TECHNOLOGY REQUIRED

A device with a web-browser – PC, Mac or Chromebook – or phone or tablet.

📃Summary

Students play a game which teaches about raising lambs, the uses of sheep and the ratio of single to twin lambs. The lesson ends with definitions of sheep and goat vocabulary and examples of analogies with sheep and goats. Optionally, students may complete a word journal assignment.

📚Lesson

Start with a game

Students begin by playing Making Camp Navajo. You can just copy and paste these instructions into your Google classroom or other system, or just copy and show in a projector on the board – old school rules!

You can assign your students usernames and passwords or you can send us a list and we will register your students for you. Email the list to growingmath@7generationgames.com . Your students can create their own usernames and password but we do not recommend this, mostly because they will forget what they entered.

Play Making Camp Navajo

There are three activities students should play. If you have not played before, the game will start you at the introduction. If you are a returning user, log in and click on the Life tab.

Earn page with choices of Numbers, life and random

Learn about sheep in Navajo daily life

On the LIFE page, you’ll see two photos with sheep in them. Play both of those sections.

Next, go to the numbers page and pick this option to learn a little more about sheep.

Many lambs

Now that you have read the instructions, here is the link to go to Making Camp Navajo.

Learn the vocabulary

Now that students have learned about sheep, let’s learn some sheep and goat vocabulary using this Google slides presentation. The presentation ends with two examples of analogies, then asks the students to give their own examples of analogies.

Assessment

This lesson has two types of assessment. Making Camp Navajo automatically records students answer to problems in the three game activities, assessing the Diné and math standards. The analogies produced by students address the ELA standard.

Differentiated Instruction

For students who struggle with vocabulary, including English learners, you may wish to include a word journal assignment. Some teachers call it a personal dictionary. Regardless, the goal is the same, for students to record new words, give a dictionary definition and “make the word their own”. This can be done by rewriting the definition in their own words, using the word in a sentence or including an illustration of the word.

Two dictionary sites to recommend for definitions are below. An added bonus to mention to students is that they can hear words pronounced.

Since students often ask for an example, here is an example you can link in your lesson.

The personal dictionary assignment, with all links, can be found here. Feel free to copy and paste into your Google classroom or other site, or print out for your class.

Geometry and Ledger Art

Leave a reply

by Avis Prentice and AnnMaria De Mars

📖 Standards

CCSS.MATH.CONTENT.7.G.A.2
Draw (freehand, with ruler and protractor, and with technology) geometric shapes with given conditions. Focus on constructing triangles from three measures of angles or sides, noticing when the conditions determine a unique triangle, more than one triangle, or no triangle.

⏰ Time

90-120 minutes, including time students spend on creating shapes, measurement and creating winter count artwork

📲 Technology Required

A computer with project/ smart board for viewing as a class or computer or mobile device for viewing videos at home is required. Art project can be done on Google Slides or PowerPoint or with markers and paper or construction paper, glue and scissors. Paper bags (optionally) can be used to simulate a hide background.

📃 Summary

Students begin by watching two videos that appear to be unrelated – on Native American ledger art and using a protractor to measure angles. These are explained in the presentation, that art can take many forms. Vocabulary and basic facts regarding angles are introduced. Students use an online app to create angles with different lengths of lines. After measuring lengths and angles of their shapes, students create artwork for their own event and a classroom ‘winter count’. Use of angles in computer animated art is explained. The session ends with assessment of students’ knowledge of measurement of angles.

📚 Lesson

Watch video on Native American Ledger Art

Watch to 5:07

Students will watch the video to the point of 5:07 , where the curator says to think of an event you really want to remember.

Watch video on using a protractor

Explain basic concepts and vocabulary of measuring angles

This 31-slide deck explains degrees as a measure of rotation, defines acute, obtuse and right angles and obtuse, acute and right triangles. Instructions are given for students creating their own ledger art. Available as Google slides here or as a PowerPoint Presentation here.

Students use an online app to create triangles from different lengths of lines.

Example from the GeoGebra app

In this exploratory activity, students should learn that a triangle cannot be created from any three lines. They will also get practice creating different angles and seeing the shapes of triangles with different angles. This activity is recommended but can be skipped if students do not have access to devices. Alternatively, the teacher or a student can create angles with result shown on a smart board/ projector.

Students create and measure shapes

As instructed in the presentation, students create lines, triangle and circles. They measure the diameter or radius of circles, length of lines and angles of triangles. Students write a description of their shapes using mathematical terms.

Students create their own artwork to commemorate an event

Students will use the shapes created in the previous activity to create original work. They will present their artwork to the class and explain its meaning.

Students watch a video on winter count

Emil Her Many Horses explains the creation and meaning of the winter count

Students combine their events to form a classroom record

Individual student events can be combined on poster board, included in a single Slides or PowerPoint document. Dr. Vivian Young recommends using large brown paper bags to simulate hides, crumpling and tearing around the edges to give more of a hide appearance.

End with presentation

Finish the slide presentation by informing students that their measurements are the first step a software developer would take in turning their artwork into computer animation for a game or website. They have been programming and did not even know it!

Calendar Assignment

In this assignment, you will be creating a personalized calendar using Google slides. Your calendar must consist of a minimum of 13 pages an include the following:

  1. A title slide with introduction of the topic.
  2. A page for each month with:
    1. An image related to your topic
    2. Text explaining the image and its relationship to the topic.
    3. A link to a source for the image and information on the page.

Presentation to Explain Modifying Template

Use this brief presentation to explain how to change the background on a slide and how to add images. It uses the 2022 calendar template as an example.

There are many, many Google Slides calendar templates you can find on the web. Many of these are great, some cost money, some are for 2021 and some have broken links. So, we added an example here that you, on the topic, “Indigenous”, that you can copy into your Google classroom and modify, just to make sure you would have a free template that is available and up to date. It uses a variety of methods of citing sources, from a simple web link in January to APA style in May.

The sample calendar as a PDF is found here.

Make a personalized gift

Janna Jensen, IT specialist from North Dakota, laminates each page in the calendar and binds the pages for a personalized gift from students to parents or other special people in their lives. If you have limited funds, you can just laminate the first and last page for durability, or skip lamination altogether if you don’t have a laminator.

If, like me, you don’t have a binding machine, you can just use a 3-hole punch and twist ties from cables or bags of bread. Ask the lunchroom staff to save some for you.

My first time ever using a laminator.

Make this assignment your own!

I highly recommend encouraging your students to improvise with this assignment. They can find another template on line, insert pages in between months so that each month has a large scale image at top – the possibilities are endless.

⏰ Time

30-40 minutes

📲 Technology Required

A projector or smart board is required to show the Google slides presentation in class. It can also be shown using any web meeting software for remote learning. The random candy generator can be used by students in anything with a browser, including computers, tablets or phones. This activity is optional. It’s actually more fun with fun-size bags of candy like Skittles or M & M’s.

📃 Summary

Students watch a video or hear a presentation explaining using long division to convert fractions to decimals. A second method of using place value is discussed when the denominator is tenths, hundredths or thousandths. Students then play a game that teaches converting fractions to decimals and end with an activity finding the decimal representing each color in a bag of candy. A simulator is included if no bags of candy are available!

📚 Lesson

EITHER watch the video below

This is a 7-minute video that gives the steps in converting fractions to decimals, with multiple examples, using both long division and place value.

OR Use this Google Slides Presentation

The Google slides presentation covers the same material as the video with the same examples. The steps in the long division problems are animated in the presentation. If you prefer a PowerPoint presentation you can find that here. Both can be viewed from these links or you can copy into your own Google drive or download to modify for your class.

The presentation and video both include two sample problems to work as a class.

NOTE: The presentation includes an activity converting fractions to decimals using candy or a random sample application.

Play a Game

On mobile devices

Play the Empiric Empire game for 10 minutes. This game teaches fractions and decimals in the context of concepts from epidemiology such as prevalence, incidence and mortality rate. This game is available for iPad, iPhone or Android.

On Chromebook

Don’t have any of those devices? Play the Minnesota Turtles game for five minutes. After the game (it’s short), assign these problems:

  1. The game says that 5/9 = 56% – prove it using long division. Is this a repeating or terminating decimal? HINT: Remember that 56% = .56
  2. The game says that 4/9 = 44% – prove it using long division. Is this a repeating or terminating decimal?
Simulated Candy Bag

Convert fractions with Candy

The Google Slides/ Powerpoint ends with an activity where students use a pack of candy to find fractions, convert those fractions to decimals and graph the result. If you don’t have time / forgot to buy bags of candy, you can use a simulator here. Random fact: The average fun-size bag contains 12 pieces of candy. There is a link for plain graph paper in the slides. If you’d prefer graph paper with fractions and decimals already entered, this page is divided into sixteenths.

Assessment

This lesson includes three types of assessment. There are the problems completed together in class, included within the presentation or video. There are the problems completed within the Empiric Empire game which you can see in the teacher reports. Alternatively, there are the two problems assigned after the Minnesota Turtles game. There is also an assessment at the end of the slides using different colors of candy to convert fractions to decimals and chart the results.

Individualization

Assign this problem to more advanced students:

Think back to what we learned in the previous lesson about fractions, decimals and percentages being three different ways of looking at the same number. You answered the two questions below. What is a different way to prove that 4/9 = 44%/

  1. The game says that 5/9 = 56% – prove it using long division. Is this a repeating or terminating decimal? HINT: Remember that 56% = .56
  2. The game says that 4/9 = 44% – prove it using long division. Is this a repeating or terminating decimal?
