This month we began a new unit in math that focuses on using addition and subtraction to understand place value. Prior to this, students have learned how to add numbers together by counting all and then counting on. For example, 9 + 3 is solved by counting on from 9 (10,11,12 ) to reach the total. They are now learning to decompose and compose numbers to make 10 or take from 10. For example, when adding 9 + 3, if they take 1 from the 3 and add it to the 9 they can quickly add 10 + 2 using what they already know about adding numbers to 10. In class, we celebrate the different ways the children solve problems and share their thinking. Learning a variety of strategies for solving equations helps the children become more efficient in their problem solving.
We will also continue to practice telling time to the hour and half hour, and have begun to learn the names of several 3-D shapes. We are focusing on the sphere, cube, cylinder, and rectangular prism. Ask your child to see if he or she can find any of these 3-D shapes at your house!
