STRATEGY NAME: Hot math
CORE CURRICULUM/SOUTH CAROLINA STATE ACADEMIC CONTENT STANDARD & IEP
GOAL:
CCSS Grade 3- Operations and Algebraic thinking 3.OA
8. Solve two-step word problems using the four operations. Represent
These problems using equations with a letter standing for the
Unknown quantity. Assess the reasonableness of answers using mental
Computation and estimation strategies including rounding.

among third-grade students with disabilities. Teaching Exceptional Children, 35 (1), 7073.
MATERIALS/EQUIPMENT NEEDED:
1. Four types of word problem structures
2. Four types of word problem structures answer key
3. Poster board with the four types of word problems and example problems (see
attachment)
4. Whiteboard
5. Pencils
6. Notebook paper
PROCEDURE/STEPS:
1. Students look at original word problem.
2. Students pick out a different format to solve the problem- using one of the four
types of structures from poster board (see attachment)
3. Students will pick out key words that are important to solving the problem.
4. Students will solve the word problem by transferring it into one of the four
structures that are listed on the poster board (see attachment).
5. Transferring the word problem means students will take the original problem and
turn it into a shopping list, half problem, bag problem or pictograph depending on
which structure they like best.
6. Students will use one of these four structures every time when solving word
problems.
ADAPTATION CONSIDERATIONS:
For students with intellectual disability, give them only one type of word problem structure
at a time so that they can process the entire structure and understand how to use it to solve word
problems before using another structure.
RATIONALE:
Students will learn how to solve word problems by transferring the original problem into
one of the four structures listed on the poster board to help them solve word problems every time.
Four types of problem structures:
1. Shopping list problem structure: word problem is formatted to fit a shopping list.
Example: Danny needs to buy things for his science project. He needs 2 batteries, 3 wires,
and 4 magnets. The batteries cost $3 each, and the magnets cost $2 each. How much money does
Danny need for his science project?
2. Half problem structure: word problem is formatted so that the answer is divided between different
people.
Example: Dave and Todd are going to buy a large box of baseball cards. There are 42 cards in
the box. Dave and Todd will each get ½ of the cards. How many cards will each of them get?
3. Bag problem structure: word problem is formatted into groups of different items.
Example: You want to buy some lemon drops. Lemon drops come in bags with 10 lemon
drops in each bag. How many bags of lemon drops should you buy to get 32 lemon drops?
4. Pictograph problem structure: word problem is formatted into pictures to find solution.
Example: Gloria collects teddy bears. She made a chart to show how many teddy bears she
had. Each picture of a bear stands for 4 bears. For her birthday, Gloria got 3 more teddy bears. How
many bears does she have now?
Answer key to four types of problem structures:
1. Danny needs $23.00 for his science project.
2. Dave and Todd will both get 21 baseball cards.
3. Four bags of lemon drops.
4. Gloria has 27 teddy bears.
