About the Mathematics in This Unit

Dear Family,

Our class is starting a new unit in mathematics called Collect, Count, and Measure. The focus of this unit is on counting and measuring. Students line up craft sticks or cubes to measure the length of objects, including the length of their shoes. They develop visual images for quantities up to 10 as they roll dot cubes, work with Ten Frames, and find many different ways to arrange and describe a set of 5 to 10 tiles.

Students count and compare quantities throughout this unit. These activities support students as they make connections between counting and combining, which helps them begin to add and subtract small numbers. For example, they solve simple story problems and play games that ask them to figure out the total when 1, 2, and 3 are added or when 1 is taken away.
