• Direct Modeling – Act out the problem.– Follow sequence of the action in a problem.– Represent sets with materials (unifix cubes, tally

marks, etc.)• Counting Strategies

– Hold one number in the head.• Derived Facts/Number Facts

– Doubles +1, -1, +2, and -2– Sums of 10 (8 + 3 = 8 + 2 is 10 plus 1 more = 11)

Introduction to Student Strategies

• Watch Video II - Students Addition and Subtraction Strategies.

• What is the problem type?

• Which strategy did the student use?

Children’s Solution Strategies

• Children in any class will be at different levels of understanding and will use different strategies to solve the same problems.

• Children naturally progress through the levels without direct instruction if children have the

opportunity to explain their mathematical understanding.
