Description |
Hooray Equal Groups | Students will learn how to represent and count equal groups through the use of literature and situational story problems. Using the book Each Orange Had 8 Slices, students will use manipulatives to find the total number of objects in a collection of equal groups. Students will learn to write corresponding repeated addition equations. |
Which Rectangle is Bigger? | Students will learn how to partition rectangles into equal parts and write equations to represent the parts. They will gain a basic understanding of area from the book Bigger, Better, BEST! by Stuart J. Murphy. |
Déjà Vu Addition, 2 plus 2 plus 2 | This lesson illustrates that when you have a rectangular array of objects, you can determine the sum of the objects by using a repeated addition equation. This builds a foundation for multiplication. |
Array Addition | This is a lesson in which students will practice making rectangular arrays and writing equations, with and without story problems, using repeated addition to find the total number of objects in each array. This lesson is designed to help prepare students for multiplication. |
I Array + You Array = Arrays! | An engaging activity that includes using repeated addition to find the total number of objects in equal groups and representing the total number of objects using arrays and equations. |
