This Story of 100: Multiplication and Division is designed to be used after reading One Hundred Hungry Ants by Elinor J. Pinczes. It is not completely essential to have read the book, but it will definitely help students to understand the concept more thoroughly, help make the activity more meaningful, and is a great way to integrate Language Arts with Math :) **THE BOOK IS NOT INCLUDED**
Designed for 3rd grade, but could definitely be used for revision/remediation for 4th!
The book deals primarily with division (the ants dividing up into lines to go to a picnic), but I have included multiplication because it provides a great opportunity to show students the relationship between multiplication and division.
The Story of 100 chart at the end is not a complete chart—it just focuses on the combinations discussed in the book.
I have also included 2 extension activities for your early-finishers or for those who just need that extra challenge!
Although the multiplication and division in this unit involves larger numbers than those required from memory for Grade 3 Common Core Standards, the activity emphasizes the relationship between multiplication and division. This could be aligned with Common Core Standard: CCSS.Math.Content.3.OA.C.7 Fluently multiply and divide within 100, using strategies such as the relationship between multiplication and division (e.g., knowing that 8 × 5 = 40, one knows 40 ÷ 5 = 8) or properties of operations. By the end of Grade 3, know from memory all products of two one-digit numbers.
