Try It 1. Kiara baked 30 oatmeal cookies and 48 chocolate chip cookies to package in plastic containers for her teacher friends at school. She wants to divide the cookies into identical containers so that each container has the same number of each kind of cookie. If she wants each container to have the greatest number of cookies possible, how many plastic containers does she need?

2. Joanne is campaigning for class president and plans to distribute some campaign materials: 20 flyers and 16 buttons. She wants each classroom to receive an identical set of campaign materials, without having any materials left over. What is the greatest number of classrooms Joanne can distribute materials to?

3. Jackson Stationery sells cards in packs of 11 and envelopes in packs of 13. If Kina wants the same number of each, what is the minimum number of cards that she will have to buy?

4. In preparation for a party, Brant is putting desserts onto platters. The chocolate cake is cut into 15 pieces and the cheesecake is cut into 6 pieces. If he wants to prepare identical platters without having any cake left over, what is the greatest number of platters he can prepare?

Explain It: Coordinate Grid - If you need to, use the notes. Label the grid x-axis y-axis quadrant 1 quadrant 2 quadrant 3 quadrant 4 (x, y) (-x, y) (x, -y) (-x, -y)

Explain It: How do you plot coordinate points?

Plot the Following Points Label with the letter A ( -4, 1)

B (1, -5) C( -2, -3)

Explain It: Reflection of a Point on a Number Line. to solve the problem. If you need to, use the notes.

Plot the point ( 1,4) then reflect over the y-axis.

Plot the point (-2, 3) then reflect over the x-axis

On the lines list the steps needed

Explain It: Distance Between Points(without drawing on a grid) On the lines list the steps needed to solve the problem. If you need to, use the notes. The distance between (-3, -6) and (-3, 10)

Try It: The distance between (-4, 0) and (10,0)___________ The distance between (5, -4) and (5, -9) _____________

Sara plotted the locations of the trees in a park on a coordinate grid. She plotted an oak tree, which was in the middle of the park, at the origin. She plotted a maple tree, which was 10 yards away from the oak tree, at the point ( 10, 0 ). Then she plotted a pine tree at the point

(-

2.4, 5 ) and an apple tree at the point ( 7.8, 5 ). What is the

distance, in yards, between the pine tree and the apple tree in the park? Each grid unit is equal to one yard.
