📃 Summary

Why would a Navajo sheep farmer need rational numbers? Our sheep farmer wants to build a new sheep corral. He would need to know positive and negative numbers, fractions, and decimals. This middle school lesson on rational numbers is integrated with some Navajo sheep history and is for grades 7 to 8. The examples are detailed and include word problems of rational numbers as applied to finding sheep farming profits. Operation rules are covered along with application of ratio and perimeter skills.

📚 Lesson

1. Bell ringer: Navajo Sheepherding Life

Have students watch this short spotlight video of Navajo sheepherding life in Arizona.

2. Write answers to prompts

Write a short response to it to keep in their notes for discussion during the history parts of the lesson.

  • What do you notice about the northern Arizona terrain?
  • What do traditional Navajos think of land ownership?
  • How does the grandmother, Helen, care for her animals?

3. Math Lesson on Rational Numbers

This presentation, Raising sheep and rational numbers, introduces the concept of rational numbers as anything that can be explained as a ratio. Negative numbers are illustrated both as loans a sheep farmer would take out and depth of holes in the ground that the farmer needs to consider in selecting the size of posts. Students are given rules of integer addition and subtraction to use as an aid in solving problems.

Differentiated Instruction

For students who may need a review of the basics, this video on What are Rational provides a good and entertaining refresher.

Adding and subtracting decimals — Students watch two videos explaining decimal and fraction equivalence. They are then presented with a brief reminder of natural, integer and rational numbers. A slide presentation discusses adding and subtracting decimals. The lesson ends with teacher and student-generated practice problems.

Assessment

There are five problems within the presentation to be worked as a class. Teachers can present the question and have students write the answers and then present the answers. Alternatively, for students working at home, each slide with questions is followed by worked answers.

Teachers can also see which standards students have attempted and how many problems they have answered correctly in the Making Camp teacher reports.

📃 Summary

There are 6 short videos on Google Slides topics like adding images and choosing a theme. We recommend breaking the first four videos into two separate lessons that students complete during class.

📚 Lesson

These lessons from Google for Education provide a good overview to Google Slides. These are part of the Applied Digital Skills program for which you can register your class and/or yourself or you can just select individual lessons. In our experience, students do better when the lessons are split over 3 or more days.

Day 1: Watch videos 1, 2 and 3

Learn Google Slides while creating a presentation about you. This lesson can be used as is or modified for other topics. The default assignment is for students to create an “All About Me” presentation. The first three videos explain creating a presentation, choosing a theme, inserting a title, adding text and images. You can copy the link and paste it into your Google classroom or other site used for assignments or have students watch these together as a group in class.

For younger students, these three videos may be adequate for your class requirements.

Day 2: Create a Presentation (Bells and Whistles optional)

Watch this five-minute video on Animation and Transition in Google Slides.

Create Your Own Presentation

After watching this 5-minute video, students are ready to create their own presentation. Students can create an “About Me” presentation as suggested in the Google slides or teachers can assign their own preferred topic.

Assessment

Rubric for assessment includes:

  • Student created Google slides presentation
  • Presentation includes the following elements: headers, text and images
  • Presentation uses at least one animation and one slide transition

For younger students, you may wish to eliminate the last requirement.

Google Apps Basics for Hamsters

While I have heard many teachers say,

“My students know technology better than I do.”

– Teacher who is often incorrect.

I have often found this not to be the case when it comes to Google apps. I’ve often found that students sometimes don’t want to admit that they don’t know Google apps, assuming that everyone else does.

No hamsters were available so I used my guinea pig

This is the first in a series of lessons for either teachers or students who may not be extremely familiar with Google apps.

For many years, I taught statistics in graduate programs in education, psychology, business and engineering. On a conference planning committee, we had a request that read,

“I would like a session on statistics, but not statistics for dummies. I want a session so easy that a hamster could understand it.”

So, that was the origin of my session, “Statistics for Hamsters.”

Now, maybe you are a Google apps guru and you don’t need any of this. Yay for you. Seriously, yay! Let’s hang out. Still, you may find these resources helpful to share with your students. Just copy the link into your Google classroom, which, of course, you know how to do.

If that is not you, keep reading, and we can still hang out. Especially if you bring coffee.

Google Drive and Google Doc: Super-Basics

All the Google apps lessons follow a similar format of a series of 15-30 second videos on simple tasks like opening the app, creating a new file and sharing. The lessons are 6-7 minutes but by the time your students get their computers open, log on and start the lesson we estimate around ten minutes of class time.

We have had more success with having students do these activities in class prior to an assignment that will use the app.

This is our favorite basic–basic lesson on Google Drive. From Google for Education, takes six minutes and ends with a quiz where you can test your knowledge.

Introduction to Google docs – The total lesson should take about 7 minutes.

Use what you learned

Follow up this lesson with a simple assignment in Google docs. This provides three prompts students can choose from to answer a question. They will practice creating a doc, copying and pasting from a doc (or, alternatively, saving to their drive), editing a doc and sharing it.

Note to the teacher: You should save the assignment in your Google classroom or other system and be sure to edit it to include your email before assigning to students.
