Narrative
The purpose of this activity is for students to create composite shapes and compose new shapes from composite shapes. For example, students may find that a rectangular prism can be made from four triangular prisms or from eight smaller cubes. Students then discover that they can combine two of the composed rectangular prisms to make a new rectangular prism.
Required Materials
Materials to Gather
Geoblocks

Groups of 4
Give each group geoblocks.
Display a large cube.
“This cube can be built from other shapes. See how many ways you can build a cube using other shapes.”
3 minutes: partner work time
Share responses.

Activity Synthesis
Display a cube and a composite cube—for example, a cube composed of four small cubes and one rectangular prism.
Demonstrate putting the shapes together.
“What new shape did I make with the cube and the cube I made?”
“Put your shapes together to make a rectangular prism.”
Display a rectangular prism and two triangular prisms.
“Find these shapes. Put them together. What new shape can you make?” (a cube, a rectangular block)


Concept/skill: 
Compose two-dimensional shapes (rectangles, squares, trapezoids, triangles, half-circles, and quarter-circles) or three-dimensional shapes (cubes, right rectangular prisms, right circular cones, and right circular cylinders) to create a composite shape, and compose new shapes from the composite shape. (Students do not need to learn formal names such as “right rectangular prism.”)

Answer: 
Yes. This activity asks students to compose three-dimensional shapes, using geoblocks, to create composite shapes.

Now, assess whether the following problem or activity is 'aligned' with the given Common Core standard in Mathematics.

standard_description: Apply and extend previous understandings of multiplication to multiply a fraction or whole number by a fraction.
problem_activity: Activity
The purpose of this activity is for students to practice rewriting expressions representing percent change so that they only use multiplication.
Launch
Allow students to work with a partner or individually.
Student Facing
Write an equivalent expression using the distributive property:
\(65 - 0.45 \boldcdot 65\)
\(65 + 0.45 \boldcdot 65\)
\(91 \boldcdot (1.2)\)
\(x + 0.04x\)
Evaluate by multiplying just two numbers in your calculator. Write down the expression you calculated.
130 increased by 10%
25 decreased by 30%
50% more than 38
6% less than 200
Write an equivalent expression that only uses multiplication:
\(p - 0.35p\)
\(z - 0.85z\)
\(q + 0.06q\)
\(r + 0.64r\)

Activity Synthesis
Either display the correct solutions or invite students to share their solutions. Here are sample questions to promote discussion:
“Why is it okay to rewrite an expression like
\(z - 0.85z\)
so that it looks like
\(0.15z\)
?” (Use the distributive property, or think about how an amount decreased by 85% is the same as 15% of the amount.)
“Have you heard some examples of percent increase or decrease used in the real world? What were they?” (Sample response: The news might talk about crime decreasing by 10% compared to last year, or home prices in an area increasing by 25%.)
“How is an expression representing percent increase (like
\(1.05x\)
) different from an expression representing percent decrease (like
\(0.95x\)
)?” (The coefficient is greater than 1 versus less than 1. This is a result of adding or subtracting a percentage of the original amount.)
