You multiplied 326 × 7 and got 2,042. How do you know your answer is reasonable?
A compost team packs 138 worms into 9 bins. How many worms total? Use the standard algorithm and draw a model.
Sometimes times tables (like 6, 7, 8, 9) feel trickier than others. Why do you think our brains experience some rhythms of multiplication as smooth and others as clunky? How do you make the tricky ones feel easier?
What helps you keep track of each step in the standard algorithm? How would you teach someone your strategy?

Have a conversation about this image. Be curious. Be creative. Can you see in different ways?
What do you notice about these times table? What patterns do you see in the answers?
Notice the 10s column and notice the 1s column.
What patterns do you notice if you add the digits of the product together?
How can the patterns help you remember? What strategies work for you?
