  12. number cubes to make a two-digit number and then a one-digit number.  The teacher will write the problem on the board and then use the block tens manipulative to work out the problem.

  13. 5. The teacher will ask volunteers to make subtraction problems by using the number cubes. The teacher will ask volunteers to work out the problem by using the block tens manipulative. The teacher will ask a volunteer to tell how to work out the problem.

  14. 6. Activities: Guided Practice: • The teacher will divide the students into groups to make subtraction problems together by using the number cubes, • The students will also work out the problem using the block tens manipulatives in their groups.

  15. Independent Practice: • The teacher will give each student a sheet of two-digit subtraction problems. • The students will work out the problems using the chip manipulatives.
