About the Three Sisters

Corn, beans, and squash have been grown together by many Native nations across North America for centuries. The name “Three Sisters” comes from Haudenosaunee (Iroquois) tradition. Each plant helps the others: tall corn gives the beans a pole to climb, beans feed the soil, and wide squash leaves shade the ground to hold in water and keep weeds down. The pictures in this pack show the crops, the harvest, and the clay jars and baskets used to store it.

How to Use This Pack

Each page is one picture cut into spaces. Children solve the fact in a space, find its answer in the color key at the top, and color the space. Pages 1 and 2 add; pages 3 and 4 subtract. The key gives some colors two answers, so every answer still needs working out.

In the Classroom

A calm center or morning work for Native American Heritage Month. Have children color the circles in the key first, so the key is ready to read. Talk about why corn, beans and squash were planted together while they color.

At Home

Solve a few spaces, color them, then a few more. Check each space against the key before coloring it.

Tips for Success

  • Color the key’s circles before you start
  • Solve first, then color
  • Small spaces show just the answer: find its color in the key
