Unit 5

Overview from Everyday Mathematics 

"Most of Unit 5 is devoted to extending children's understanding of, and proficiency with, addition and subtraction.  Children make up and solve number stories, helping to foster links between verbal representations and concrete, pictorial, and number-model representations."

Unit 5 has four main areas of focus: 
  • To investigate place-value concepts for tens and ones
  • To explore addition of 2-digit numbers
  • To make up and solve a variety of number stories
  • To introduce the "What's My Rule?" routine
