PRACTICE TABLE

WORD PROBLEMS

Follow the step-by-step instructions below to teach the lesson.

Progress to the next lesson when children master the current lesson.

Value mastery over speed of progression.

STEP 1

Teach children to recognize and combine groups of physical objects up to 19 (without counting). Use a variety of objects that interest children such as coins, books, dinosaurs, action figures, cars, and stuffed animals.

- Show children groups of 1-19 physical objects and have them call out the corresponding number.
- Have children show you a specified number of objects without counting.
- Combine objects per the table above and then immediately separate these groups again into their component parts. For example, 1 pencil and 9 pencils, 2 coins and 9 coins, and 9 cars and 9 cars, etc.
- When children are ready, call out problems from the table and have children combine and separate the object groups themselves.
- Children must perfectly master the operations listed in the table before proceeding to the next step of the lesson.

STEP 2

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

- Using the table above as a guide, ask children to call out the answer to questions such as, 'How many are two shoes and nine shoes?' and 'How many are nine frogs and seven frogs?'
- Continue to practice until children can recite each operation in the table with great accuracy and rapidity.

STEP 3

In this step, do not mention objects. Children add numbers directly.

- Using the table above as a guide, ask children to call out the answer to questions such as, 'How many are nine and five?' and 'How many are nine and eight?'
- Continue to practice until children can recite each operation in the table with great accuracy and rapidity.

STEP 4

Direct children to write and recite the addition problems in the table above. For example, children write and recite:

- 9 and 10 are 19
- 9 plus 10 is 19
- 9 + 10 = 19

Repeat for each combination in the table until the children master the tasks.

STEP 5

Begin to teach place value.

- Tie a group of 10 objects together (sticks, pencils, paperclips etc.).
- Say - this is a group of 10.
- Ask - 'How many objects are in this bunch?'
- When children answer '10', write the number '10' on a whiteboard or paper.
- Hold up one bunch and nine objects and ask - 'How many objects am I holding now?'
- When they answer '19', say - 'Yes, nineteen is made up of one 10 and nine 1s.
- Write the number '19.' Point at the '1' in the 10s place and say 'one 10.' Point at the '9' in the 1s place and say 'nine 1s.'

STEP 6

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

If children have difficulties, repeat the prior steps and then reassess.
