Introduction to Equal Groups and Multiplication

Multiplication begins with equal groups, not with times tables. Before students can understand 3 x 4 = 12, they need to understand that three groups of four is the same as 4 + 4 + 4. Arrays (arrangements in rows and columns) are the bridge between equal groups and the symbolic notation. This topic extends beyond the BC Grade 2 curriculum as enrichment, connecting the skip-counting and equal-groups thinking that IS in the curriculum to the formal multiplication concept that appears in Grade 3.

WHAT STUDENTS WILL LEARN
Arrange objects into equal groups and describe the arrangement
Connect equal groups to repeated addition: 3 groups of 4 = 4 + 4 + 4 = 12
Use arrays (rows and columns) to model multiplication situations
Skip-count to find the total in equal-group arrangements
Recognize multiplication as a more efficient notation for repeated addition (extension)
