Carlan wants to host a cookie party. He baked 12 cookies on a tray 3 times. Then his friends brought 30 cookies total. How many cookies are at Carlan's Cookie Party?
First, 12 x 3 = 36.
Then, 36 + 30 = 66.
Carlan has 66 total cookies at his party.
9 x 4 = 36
4 x 9 = 36
36 ➗ 4 = 9
36 ➗ 9 = 4
Use a Multiplication Property to solve the following equation.
15 x 4 = ?
Using the Distributive Property, I can Show that:
15 x 4 = ?
(10 x 4) + (5 x 4) = ?
40 + 20 = ?
40 + 20 = 60, so 15 x 4 = 60.
Estimate the following equation by rounding to the nearest ten.
117 + 22 = ?
Rounding to the nearest ten, your estimate should look like.
120 + 20 = 140
Jayla wants to draw pictures for her friends for Christmas! She drew 10 pictures a day for 8 days straight. Then, she gave away 2 pictures a day for 5 days. How many pictures does Jayla have left now?
This is a THREE step problem.
First, 10 x 8 = 80
Then, 2 x 5 = 10
Last, 80 - 10 = 70.
Jayla has 70 pictures left.
Solve all four equations:
12 x 7 = ?
9 x 8 = ?
144 ➗ 12 = ?
81➗ 9= ?
12 x 7 = 84
9 x 8 = 72
144 ➗ 12 = 12
81 ➗ 9 = 9
Use a Multiplication Property to solve the following equation
3 x 4 x 9 = ?
Using the Associative Property, one way to solve is
(3 x 4) x 9 = ?
12 x 9 = ?
12 x 9 = 108
so 3 x 4 x 9 = 108
Rounding to the nearest hundred, estimate the following equation:
922 - 265 = ?
Using estimation, your equation should look like:
900 - 300 = 600
Khydence brought pizza for the whole school! Khydence brought 300 slices of pizza. First, all the scholars ate 219 pieces of pizza. Then, the 9 teachers split the rest of the pizza between themselves. How many slices of pizza did the teachers each get?
This is a two step problem.
First, 300 - 219 = 81
Then, 81 ➗ 9 = 9
Each teacher got 9 slices of pizza.
