30 Task Cards to practice solving 2-step multiplication expressions with missing factors.
Each card has 1 expression with a missing factor represented by a variable. There is also a given value for the variable on each card. Students will replace the variable in each equation with the given value and then solve for the product.

Uses for these 30 task cards are limited only by your own creativity! However, here are some ideas to get you started.

**Post the cards around the room. The students Read the Room until they have answered them all on the answer sheet.
**Divide the cards up and give some to each partnership or group of students to complete. Have them report their answers and procedures to the class.
**Activities for Centers or Stations
**Flash Card review activities
**Kagan inspired structures such as Quiz-Quiz-Trade, Fan and Pick, Showdown, Rally Coach, etc.
**Quiz-Style Game Show question cards
**Small Group intervention practice
**Testing Review games/activities
Solve two-step word problems using the four operations. Represent these problems using equations with a letter standing for the unknown quantity. Assess the reasonableness of answers using mental computation and estimation strategies including rounding.
Apply properties of operations as strategies to multiply and divide. Examples: If 6 × 4 = 24 is known, then 4 × 6 = 24 is also known. (Commutative property of multiplication.) 3 × 5 × 2 can be found by 3 × 5 = 15, then 15 × 2 = 30, or by 5 × 2 = 10, then 3 × 10 = 30. (Associative property of multiplication.) Knowing that 8 × 5 = 40 and 8 × 2 = 16, one can find 8 × 7 as 8 × (5 + 2) = (8 × 5) + (8 × 2) = 40 + 16 = 56. (Distributive property.)
Determine the unknown whole number in a multiplication or division equation relating three whole numbers. For example, determine the unknown number that makes the equation true in each of the equations 8 × ? = 48, 5 = __ ÷ 3, 6 × 6 = ?.
