• 3 + 6

• 30 + 6

• 13 + 6

product

• the result of division

• the result of multiplication

• the number being multiplied

• area model

Answer explanation

Choose TWO equations that describe the multiplication model.

• 6 groups of 2 is 12

• 2 x 6 = 12

• 6 + 6 = 12

• 2 groups of 6 is 12

What is the ? in the problem below 6,923 x 7
(? x 7) + (900 x 7) + (20 x 7) + (3 x 7)

• 6
• 60
• 600
• 6,000
