Hundred chart puzzles: a 20-minute 1st grade place value activity
What it is: a 1st grade math activity where students put a hundred chart back together after it has been cut into puzzle pieces. To fit the pieces, they use patterns: down a column the tens go up by one, across a row the ones go up by one.
Time: about 20 minutes. Grade: 1st grade.
Materials: hundred charts printed on card stock and cut by an adult into 6 to 8 chunky pieces, one set per pair, kept in envelopes.
- Show a whole hundred chart. Ask: "What changes when you move one step right? One step down?"
- Hand out the envelopes. Pairs put the puzzle together, starting with the piece that has 1.
- Ask pairs to explain how they knew where a piece goes: "This one has 45, so 55 must be right below."
- Cover a few numbers on the finished chart with sticky notes. Partners say the hidden numbers.
- Swap envelopes and try another puzzle.
Safety: an adult cuts the charts before class.
Differentiation: students who need support work with a 1 to 50 chart in 4 pieces. Students who are ready get a chart with only a few numbers printed on each piece. English learners can use the words row, column, more and less.
Quick check: point to 36 and ask a student which number is above it and which is below it.
Save this activity to your library so it is ready when you need it.
