Teacher tip
Read each row as “3 groups of 4” before writing 3 × 4. The words bridge addition and multiplication.
How to use it
- Start with two minutes of skip counting out loud for the tables on the sheet.
- Let kids draw quick arrays for any fact they don’t know yet.
- Do the first problem together under a document camera, then let kids finish on their own.
Watch for
Lost place value in the second partial product. Remind kids to write the zero first.
Talk about it
- How can 5 × 6 help you with 6 × 6?
- Which problem was the hardest? What made it hard?
