Arrays and Division
Donut Division
Materials Needed:
- Printable donuts, play dough doughnuts, or real donuts
- Printed order cards OR index cards (write the orders on them)
- Optional: Coloring supplies to color donuts
- Optional: Muffin tins, egg cartons, or grid paper (to model arrays)
Project Setup:
Tell the learners they’re opening a donut shop. Customers place orders, and they need to figure out how to pack the orders using multiplication and division.
Learning Goals Reinforced:
- Interpreting the unknown in division
- Understanding the relationship between multiplication and division
- Using arrays as visual tools
- Applying math to real-world contexts
1. Array Station – "Pack the Order"
Learners are given cards with a total number of donuts and told how many go in each row/package/boxes. Using the pretend donuts they must pack the order (you could use muffin tins, egg cartons, or printable grids to do this).
Optional: Learners write in the division/multiplication problem OR they match the equations cards and fill in missing numbers.
2. Missing Factor Bakery Board
Learners are given cards with a total number of cookies and then told how many groups (boxes, trays, shelves) they are using. They must figure out how many items go in each group (the size of the group) by physically “filling” them with the donuts.
Optional: Learners write in the division/multiplication problem OR they match the equations cards and fill in missing numbers.
3. Create Your Own Problem
Students draw a bakery item, decide how many they baked, and write a division problem for someone else to solve. They model it using arrays or manipulatives.
4. Extensions
Learners could also practice their money skills by deciding how much their donuts would cost and practice buying them from each other.
