• In Unit 1, students investigate the relationships between numbers and operations as they informally explore the concepts of addition and subtraction.
  
• In Unit 2, students extend their understanding of relative magnitude as they informally explore and compare measurements of different boxes.
  
• Unit 3 further builds on students’ knowledge of whole numbers as they use multiples of five and ten to compose and decompose numbers and solve problems.

Throughout the units, students develop effective group skills.
