About the Mathematics in This Unit

Dear Family,

Our class is starting a new mathematics unit about multiplication. In this unit, students review multiplication facts and solve problems by using arrays, such as the examples below. They also solve problems about factors of a number and number relationships, such as this one: If 25 is a factor of 100, will 25 also be a factor of 300? How do you know? Students are introduced to multiplicative comparison problems.

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

Benchmarks/Goals	Examples
Use multiplication to solve multiplicative comparison problems.	Franco's daughter is 2 feet tall. Franco is 3 times as tall as his daughter. How tall is he? d
Determine whether numbers up to 100 are prime or composite.	Is 49 prime or composite? How do you know?
