Divide with 11 and 12

Essential Question What strategies can you use to divide with 11 and 12?

UNLOCK the Problem

  • Question 1 (request help)

    Tara collects 60 postcards. She arranges them in 12 equal stacks. How many postcards are in each stack?

    Divide. 60 ÷ 12 = \(\blacksquare\)

One Way

Use a multiplication table.

  • Question 2 (request help)

    Since division is the inverse of multiplication, you can use a multiplication table to find a quotient. Think of a related multiplication fact.

    12 x \(\blacksquare\) = 60

    • Find the row for the factor 12.
    • Look across to find the product, 60.
    • Look up to find the unknown factor.
    • The unknown factor is 5.

    Since 12 x 5 = 60, then
  • 60 ÷ 12 =    

Another Way

Use repeated subtraction.

  • Question 3 (request help)

    • Start with 60.
    • Subtract 12 until you reach 0.
    • Count the number of times you subtract

    You subtracted 12 five times.
  • 60 ÷ 12 =     So, there are 5 postcards in each stack.
