PRACTICE TABLE #1

PRACTICE TABLE #2

PRACTICE TABLE #3

Teach children to add columns of numbers.

When mentally adding columns consisting of numbers such as '6, 8, 3, 9', do not allow children to say '6 and 8 are 14, 14 and 3 are 17, 17 and 9 are 26, etc..' Instead train children to only speak the results '14, 17, 26.'

Have children practice until they perfectly master the task.

STEP 1

- Direct children to mentally add the columns below, speaking aloud the results only of each operation.
- Have children add columns from bottom to top for additional practice.
- Exercise #1: Add the columns aloud from top to bottom and bottom to top. For example, for the first problem top to bottom, students say '2, 3.'

STEP 2

- Exercise #2: Add the columns aloud from top to bottom and bottom to top. For example, for the first problem top to bottom, students say '9, 10.'

STEP 3

- Exercise #3: Add the columns aloud from top to bottom and bottom to top. For example, for the first problem top to bottom, students say '4, 6.'
