Three different strategies are shared. Children are very clear in explaining their strategies. • Record thinking on handout provided • What type of problem does the teacher use? • 20 minutes in length

  13. Writing Our Own Number Sentences to Encourage Students to Use Relational Thinking • Grade Levels (K-1, 2-3, 4-5) • Use Emma’s problems as examples • Use relationships that are more complex for older students while retaining the relationship structure and not “tricky” computation. • Post on chart paper • 20 minutes

  14. Homework • Understanding the Properties of Arithmetic-A Prerequisite for Success in Algebra • Use number sentences in your classroom and continue to visit and revisit • Bring back examples and be ready to share how the students did
