2. Multiply Whole Numbers Times Fractions Using Two Methods
METHOD #1 1 2 x 12 = _____𝑥_____ 2
METHOD #2
Divide by a Common Factor and Solve
1 2 x 12 = 1 𝑥 12 2
Did you get the same answer using both methods?

METHOD #2
Divide by a Common Factor and Solve
16 x = 16 𝑥 1 4
METHOD #1
16 x = _____𝑥_____ 4
16 x = _____𝑥_____ 4
16 x = 16 𝑥 3 4
2 3 x 9 = _____𝑥_____ 3
2 3 x 9 = 2 𝑥 9 3
24 x = _____𝑥_____ 6
24 x = 24 𝑥 5 6

5. Problem 1: Build a Solid from a cube
Concept Development
Problem 1: Build a Solid from a cube
Shade a square on your centimeter grid paper with an area of 4 square units. This is going to be the foundation for our structure. Place 4 cubes directly on top of that square. Add more layers!

6. Problem 2: Build solids with a given volume with cubic centimeters
Concept Development
Problem 2: Build solids with a given volume with cubic centimeters
Since this is a cube with each edge measuring 1 centimeter, we call this a cubic centimeter. These cubes can serve as a unit to measure the volume of your solid, the amount of space it takes up. Just like we use squares to measure area in square units, we use cubes to measure volume, in cubic units. Example: 4 cm3

7. Problem 2: Build solids with a given volume with cubic centimeters
Concept Development
Problem 2: Build solids with a given volume with cubic centimeters
Work with a partner to build three different solids with a volume of 4 cubic centimeters. Move on to make 5 cubic centimeters….. 6 cubic centimeters!

8. Problem 3: Represent solids on isometric dot paper
Concept Development
Problem 3: Represent solids on isometric dot paper
Now we are going to draw what we build! We will use isometric dot paper to draw our structures. We will start by drawing 1 cubic centimeter.
Step 1: Connect four dots to make a rhombus. This will represent one square face of the cube, viewed at an angle.
Step 2: Draw three straight segments to the right from the two vertices on the top and the one on the bottom right.
Step 3: Draw two segments to represent the missing edges.

9. Problem 3: Represent solids on isometric dot paper
Concept Development
Problem 3: Represent solids on isometric dot paper
Now let’s draw 2 cubic centimeters.
Step 1: Connect four dots to make a rhombus. This will represent one square face of the cube, viewed at an angle.
Step 2: Add another rhombus that shares its right edge, just like your cubes.
Step 3: Draw four straight segments to the right from the three vertices on the top and on the bottom right.
Step 4: Draw three segments to represent the missing edges.

10. Problem 3: Represent solids on isometric dot paper
With a partner, build a structure with no more than 10 cubes each. Then draw your partner’s structure on dot paper. Help each other figure out if it matches what you built.

11. Application Problem
Jackie and Ron both have 12 centimeter cubes. Jackie builds a tower 6 cubes high and 2 cubes wide. Ron builds one 6 cubes long and 2 cubes wide. Jackie says her structure has the greater volume because it is taller. Ron says that both of the structures have the same volume. Who is correct? Draw a picture to explain how you know. Use grid paper if you wish.
