I LOVE this lesson! For years my students struggled through multi-digit multiplication (23x25 or 326x15). They always forgot the steps or what numbers to multiply together.
Now I teach "turtle multiplication" and it has changed everything!
Turtle multiplication is really just the basic algorithm we were all taught. However, when paired with a gimmicky turtle for whatever reason students are able to remember how to find the product much easier.
This lesson has saved me from pulling my hair out year after year trying to teach multi-digit multiplication! Your students will also enjoy it! :)
