Distributive Property
of Multiplication over Addition

Use a LEVER made of LEGO materials to fling a button onto a game board with numbered areas.
First fling is a, second is b, and third goes in the place where c is.
Each student flings 3 times for each of 5 scores.
See who gets the greater total points.
Find out which team gets the highest points for all 10 scores.
Person 1
a(b+c)=
ab+ac
Person 2
a(b+c)=
ab+ac
Example:  5( 3+ 7) =
 Add first    5( 10 ) = 50
Check by distributing        5(3) + 5(7) = 15 + 35 = 50
50
Example:  7( 5 + 3) =
7( 8 ) = 56
7(5) + 7(3) = 35 + 21 = 56
