Each child needs to:
2. Know how to solve unfamiliar addition and subtraction problems
3. Know the pre-facts with automaticity: +-0, +-1, doubles to 10, a number away from itself
4. Have a firm understanding of what a number family is
5. Know how to find the partners for a given number
6. Know how to generate the addition and subtraction facts for the partners in a family
7. Know how to use the Tub activities
8. Know how to organize materials and how to turn in completed work
The Teacher needs to:
1. Organize materials:
2. Plan lessons for students to prepare them for Number Families. See: "What each student needs to know..." (above)
3. Determine your record keeping system.
4. Decide how the tubs will work in your
classroom. You should start with 20 to 30 minute blocks with all children
working on their packet or in the tubs. You are then free to help the
children learn the whole system. After the kids are well established,
you can use the tubs as a part of a rotation or as a center.
5. Pre-test the kids to place into the appropriate number family.
Give test 5, allowing 1 minute or 1 minute 15 seconds, depending on the
small motor skills of your students. Continue testing (6,7,8...) students
who pass tests with a score of 18 or higher correct.
