The principle focus of Unit 2 is exploring various applications for multiplication, including rectangular array patterns and work with factors, factor pairs, multiplies, prime numbers, and composite numbers. Students will learn to interpret multiplication equations as multiplicative comparisons and they will work with patterns found in square numbers, multiples, factors, and "What's My Rule?" tables.
Measurement work in Unit 2 is also tied to multiplication. Working with units of time, students multiply to convert from hours to minutes and minutes to seconds. They will further explore the area formula for rectangles and also, will build on their study of geometry by identifying properties of shapes. Students will explore properties of angles and triangles as well as begin to classify and sort quadrilaterals.
