The week of September 17

Grade 1 Math
This week students will learn that when a number is added to zero, the sum is always that number. Children will use manipulative, pictures and symbols to work on addition problems with zero. We will also learn about the commutative property of addition that the order of the addends does not affect the sum.students can use cubes to model numbers and compare the sum.Model cube trains using two different colors and turn the train around so that the cubes appear in different order, students  learn the concept that changing the order of the addends does not change the sum. We will complete worksheet in class.
