Mathematics (2019) Grade(s): 3

MA19.3.12

Use concrete materials and pictorial models based on place value and properties of operations to find the product of a one-digit whole number by a multiple of ten (from 10 to 90).

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.
