Lesson objective: Students will be able to fluently add ten to a 2-digit number.

This lesson helps to build fluency with adding 10. Cubes and hundred charts are used here because students can access a concrete or abstract representation. This work develops students' understanding that 10 can be added to any two-digit number without having to count on.

Students engage in Mathematical Practice 5: Use Appropriate Tools Strategically as they choose their preferred tool (cubes or hundred charts) to practice adding 10 fluently.

Key vocabulary:

  • add
  • more
  • ones' place
  • place value
  • tens' place

Special materials needed:

  • cubes (towers of 10 cubes and loose cubes)
  • hundred charts (1 per pair of students)
  • number cards (1 set per pair of students)
  • recording sheets (1 per student)
