Use these number story cards to give scholars practice with arrays and number models. There are 12 cards here, each with a simple object scenario for learners to apply mathematically. Mathematicians are given the number of rows and how many objects are in each row and then have to solve for the total number of the object. They draw the array and write a number model. The given numbers don't exceed 10, and some are written in word form while others are numeric. This could be an introduction to multiplication.
A great resource gets kids to start thinking about multiplication in a developmental way while building strong number sense and operational skills. Each slide contains scattered counters, which are then put into neat rows (making arrays), learners then write all the ways they can make that number, including multiplication and repeated addition. They complete three problems as a class and 5 on their own.
Pupils identify and define various mathematical properties, such as Commutative Property of Addition and Multiplication, and the Associative Property of Addition. They also reason and communicate mathematically by making mathematical connections. Finally, 3rd graders create their own simple array and exchange with a partner.
Third graders begin learning about multiplication using arrays. In this multiplication with arrays lesson, 3rd graders interact with tiles on the overhead as they follow the teacher in making arrays. They write multiplication sentences based on the arrays and complete an assessment by show arrays on geoboards.
