Build With Pieces

See how a set of small pieces can be built into many new objects.

A toy built from snap cubes looks like one thing, but it is made of pieces. Build With Pieces follows marked cubes as a build is taken apart and rebuilt into something new, so students see that the same pieces can make a different object.

Row and One Below Three marked snap cubes joined in a row on a table, with a fourth cube joined below the left end.
The same pieces can make a new build.

What students investigate

Students learn that one joined toy can have many pieces, that taking a build apart leaves each piece whole, and that marks help find the same pieces again. They see how pieces connect where their faces fit together.

Then the same pieces make a new build. Students learn that changing the joins changes the shape, while turning a whole build keeps the same joins. They check for every piece from the start, compare three stages of a rebuild, and use evidence to explain how a build changed.

Who it is for

Build With Pieces is written for Grade 2 and is a natural partner for a box of snap cubes or building bricks in the classroom. Students can rebuild what they see on a card and check their own pieces.

The words piece, connect, rebuild, stage and evidence are taught on Learn cards before any question uses them.

10 learning ideas, one at a time. Each one is a silent animated Learn card, then Review and Mastery questions.

  • Review. 30 practice questions with feedback. Ideas a student misses come back.
  • Mastery. 30 questions to show what each student knows on their own.
  • Certificate. A student who finishes can print a certificate or save it as a PDF. It shows first-try Review and Mastery results and the ideas that needed a retry.

Standards connections

These cards support parts of the following NGSS performance expectations. They do not replace hands-on investigations.

  • 2-PS1-3 — core ideas

Questions teachers ask

Do students need building blocks?

No, the cards work on their own. Real cubes make a great follow-up, because students can try each rebuild with their hands.

How does it show the change?

Cards compare the start, middle and end stages of a rebuild side by side, with marks on the cubes so the same pieces can be followed.

How do I open it after buying?
