ATOS 3.2 AD470L

What is probability?


Help K-5 students answer this essential question (and meet the Common Core State Standards) with the Teaching STEM lesson plans for this mentor text: A Very Improbable Story by Edward Einhorn.

 Students will examine the essential question, “What is probability?” They will become familiar with probability by making predictions and then testing them. Each student will keep data about the predictions and look for patterns while using a spinner to see which color the arrow will land on. They will use vocabulary related to probability and write a number sentence to show their information.

The Library Activity begins on page 164. The Collaborative Teacher Activity is on page 167.

Extension Activities (sample)

 1. Do the activity using M&Ms found at this website and graph the results.

2. Make a spinner with 5 colors or use a die to test probability. Have them set up the trials and record their results. Have them write about differences or similarities they notice as trials and the amount of choices increase.

3. After reading the book, have the students write a short description of the main idea of the book. Use the phrase, “I am a mathematician. I know that _________.”
