Unpacked Content

Knowledge

Students know:

a variety of strategies or tools to find products (skip counting, properties of operations, concrete materials, number lines, arrays, etc.).

Skills

Students are able to:

Find the product of a 1-digit factor and multiple of 10 (from 10 to 90).
Use concrete materials and pictorial models to find the product.
Use properties of operations to find the product.
Justify products.

Understanding

Students understand that:

A one-digit number multiplied by ten gives a multiple of ten. Ex: 6 x 10 = 60 is the same as that number of ones (60) or that number of tens (6 tens).
Adding a zero to the product of two non-zero whole numbers does not demonstrate the relationship between the product and its place value.
