Problem/activity:
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.

problem_activity: Narrative
In this activity, students identify the nearest multiples of 10 and 100 for given three-digit numbers. They may do so by using the number lines from earlier, but they may also start to notice a pattern in the relationship between the numbers and the nearest multiples and decide not to use number lines. The work here prepares students to reason numerically in the next lesson.
When students notice and describe patterns in the relationship between the numbers and the nearest multiples of 10 or 100, they look for and express regularity in repeated reasoning (MP8).
MLR2 Collect and Display:
Circulate, listen for, and collect the language students use as they make sense of “close to” and “about.” On a visible display, record words and phrases such as: “almost 100, but not exactly,” “only 1 away from 100,” “less than 5 away.” Invite students to borrow language from the display as needed, and update it throughout the lesson.
Advances: Conversing, Reading
Launch
Groups of 2
“Let's find more multiples of 10 and 100 that are close to some numbers.”
“Notice that no number lines are given. See if you can still find the nearest multiples of 10 and 100 without them. If you need to, you can still use a number line.”
Activity
“Work with your partner to complete these problems.”
5–7 minutes: partner work time
Monitor for students who use the following strategies to highlight:
Reason about the midpoint between a multiple of 10 or a multiple of 100 (5 or 50) to determine which multiple is closer, such as, “568 is closer to 570 because 565 would be the middle point between 560 and 570.”
Use place value patterns to determine which multiple is closer, such as, “Since the 1 in 712 is less than 5, it tells me that the number is closest to 700.”
Pause for a brief discussion before students complete the last problem.
Select previously identified students share the strategies they used to find the nearest multiple of 100 and the nearest multiple of 10.
“Now take a few minutes to complete the last problem.”
2–3 minutes: independent work time
Student Facing
Is 349 closer to 300 or 400?

Without locating a given number on a number line, how did you decide:
the nearest multiple of 100?

Advancing Student Thinking
If students don’t identify the closest multiple of 10 or 100, consider asking:
“What have you tried to find the closest multiple of 10 (or 100)?”
“How could you use a number line to find the closest multiple of 10 (or 100)?”
Activity Synthesis
Invite students to share their responses and reasoning for the last problem.
