Content Standard(s):
Mathematics

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
Evidence Of Student Attainment:
Students:
  • Efficiently use strategies based on place value and properties of operations to multiply one-digit numbers by multiples of 10 (from 10-90) and justify their answers.
Teacher Vocabulary:
  • Multiply
  • One-digit
  • Multiple of ten
  • Place value
  • Properties of operations
  • Product
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.
Diverse Learning Needs:
Essential Skills:
Learning Objectives:
M.3.12.1: Model place value by multiplying vertically.
M.3.12.2: Model properties of operations by multiplying horizontally.
M.3.12.3: Recall basic multiplication facts.
M.3.12.4: Recall multiplication as repeated addition.
M.3.12.5: Apply properties of operations as strategies to add.

Prior Knowledge Skills:
  • Identify place value for ones, tens and hundreds.
  • Recall basic multiplication facts.
  • Recognize properties of operations.
  • Demonstrate that multiplication is the same as repeated addition.

Alabama Alternate Achievement Standards
AAS Standard:
M.AAS.3.10 Using vocalization, sign language, augmentative communication, or assistive technology use concrete materials and pictorial models to model whole numbers.
