Illustrative Mathematics | v.360 Curriculum

Problem 1

Draw a tape diagram to match each equation.

\(5(x+1)=20\)
\(5x+1=20\)

Problem 2

Select all the equations that match the tape diagram.

Tape diagram, 1 part labeled 8, 6 parts labeled x, total 35.

\(35=8+x+x+x+x+x+x\)
\(35=8+6x\)
\(6+8x=35\)
\(6x+8=35\)
\(6x+8x=35x\)
\(35-8=6x\)

Problem 3

ForLesson 2: Reasoning about Contexts with Tape Diagrams

A school ordered 3 large boxes of board markers. After giving 15 markers to each of 3 teachers, there were 90 markers left. The diagram represents the situation. How many markers were originally in each box?

Tape diagram. Three equal parts labeled, x minus 15, total 90.

Problem 4

ForLesson 12: Similarity

These 2 triangles are similar. Find side lengths \(a\) and \(b\). Note: the 2 figures are not drawn to scale.

<p>Two triangles. First, sides 9, b, 21. Second, sides 3, 5, a.</p><br>

Problem 5

ForLesson 3: Scaled Relationships

Kiran and Mai are standing at one corner of a rectangular field of grass looking at the diagonally opposite corner. Kiran says that if the field were twice as long and twice as wide, then it would be twice the distance to the far corner. Mai says that it would be more than twice as far, since the diagonal is even longer than the side lengths. Do you agree with either of them?

Problem 6

ForLesson 13: Adding the Angles in a Triangle

The line has been partitioned into 3 angles.

A straight line with two rays coming out of a single point.

Is there a triangle with these 3 angle measures? Explain.
