About the Mathematics in This Unit

Dear Family,

Our class is starting a new unit in mathematics called How Many Noses? How Many Eyes? The focus of this unit is on identifying attributes of data and objects; collecting, sorting, and representing data; and using data to solve problems.

Throughout this unit, students will be working toward these goals:

Benchmarks/Goals Examples
Sort a set of objects by a given attribute and order the groups based on the number in each
Using data to represent and solve a real-world problem

Are there enough chairs for everyone in our class?

A drawing shows chairs and children in four rows. Each row of chairs is above each row of children. In the first two rows, each chair is above each child. In the last two rows, one chair does not have a child below it. Text reads: more chairs than kids.
