PRACTICE TABLE

WORD PROBLEMS

Have children complete the steps below.

Have children practice until they perfectly master each task.

STEP 1

Demonstrate multiplication with various physical objects, marks on the board, and/or an abacus with counters (beads).

To teach 2x7 and 7x2, demonstrate with 14 objects of various types and ask:

- How many are 2 groups of 7 coins? (Divide the 14 coins into 2 equal groups of 7.)
- How many are 7 groups of 2 coins? (Divide the 14 coins into 7 equal groups of 2.)
- When children readily call out the correct answers, give them each 14 coins and direct them do the divisions themselves.

Represent the operations using dots or other symbols on the board. Draw the dots and ask:

- How many are 2 groups of 7 dots? (Make 2 groups of 7 dots. Circle each group of 7 dots.)
- How many are 7 groups of 2 dots? (Make 7 groups of 2 dots. Circle each group of 2 dots.)
- When children readily call out the correct answers, direct them to make the marks on the board and circle the groups themselves.

If using an abacus, demonstrate by sliding the counters to illustrate:

- How many are 2 groups of 7 counters? (Slide over 7 counters on 2 rows.)
- How many are 7 groups of 2 counters? (Slide over 2 counters on 7 rows.)
- When children readily call out the correct answers, direct them to slide the counters to make the groups themselves.

STEP 2

Children multiply objects they can't see, but can imagine (bears, mountains, trees).

Ask the following:

- How many are 2 groups of 7 suitcases?
- How many are 7 groups of 2 tangerines?

STEP 3

In this phase, do not mention objects. Children multiply numbers directly.

Ask the following:

- How many are 2 groups of 7?
- How many are 7 groups of 2?
- How many are 2 times 7?
- How many are 7 times 2?

STEP 4

Write the problems listed in the table below on the board. Show the children the symbol for times (x).

Direct children to write and then recite each of these equations as follows:

- 2 times 7 is 14
- 2 x 7 = 14
- 7 times 2 is 14
- 7 x 2 = 14

STEP 5

Repeat steps 1-4 for each combination in the table below until the children master the tasks.

STEP 6

Assess mastery by reading aloud the listed word problems and having the children mentally compute and recite the solutions.

If children have difficulties, repeat the prior phases as needed and then reassess.
