Building and Breaking Apart Two-Digit Numbers with Base Ten Blocks
A 3rd-grade practice set that guides students through building two-digit numbers with base ten blocks, drawing tens rods and ones units in T-charts, and breaking numbers into tens and ones. It includes a worked example (34) and step-by-step problems, making it well suited to a 20-30 minute math center or independent practice block.
“Build and break apart two-digit numbers - with models”
Teacher Guide & Tips
- Use this during a place value unit after students have explored base ten blocks with hands-on manipulatives, either as guided practice or as an independent station.
- Discussion question: How do you know how many tens and how many ones are in 27 without counting every single block?
- Scaffold for struggling readers: Model one problem aloud with physical blocks first, then have students label the tens and ones columns before drawing; provide pre-cut paper strips and squares if drawing is slow.
- Extension for advanced students: Ask them to rebuild a number in a different way (for example, 27 as 1 ten and 17 ones) and explain why both show the same value.
- Estimated time: About 20-30 minutes for the full set, depending on how many problems students complete with models.
