How to Use This Book
|
- Read the book and have the children complete the tasks presented in each poem.
- For children who are tactile learners, the groups of items in the book could be copied onto cardstock and cut apart. These children could physically group the items and find equal groups as necessary. (Trade a group of 4 eyes for a group of 3 eyes and 1 eye.)
- Students who can visualize multiple groupings can ring these groups using different colored markers on photocopies of the book pages.
- Students can also use numbers to list the solutions to each poem. Discussion about trading numbers (3 is the same as 2 + 1) will help students understand composition and decomposition of numbers.

Highlights and Insights
|
- The most important aspect of this book is that there are various sums of smaller numbers that equal a given number.
- Combinations modeled by the illustrations will help students who are not yet ready to figure the sums just using numbers.
- Finding a variety of ways to combine sets allows students to develop efficient counting strategies, which generalizes to column addition later on.
