Two-Step Word Problems with Mixed Operations - Gamified!
Students will be able to solve two-step, mixed operation word problems using the Read, Draw, Write (RDW) strategy.
- Ask students if they have ever played Connect Four. Ask for student volunteers to summarize the rules and object of the game.
- Tell students that after learning the Read, Draw, Write (RDW) strategy for solving word problems, they will practise by playing a game that is a cross between tic-tac-toe and Connect Four.
Explicit Instruction/Teacher modeling(5 minutes)
- Write 'Read, Draw, Write' on the board, writing the first letters with a different colour.
- Tell students that the RDW process is a strategy to help them solve word problems.
- Ask students to predict what each step means, then finish the phrases: Read the problem, draw and label a model to help you solve, and write the solution in a number sentence and a word sentence.
Guided practise(5 minutes)
- Model the RDW process using the first problem from the Word Problem Solving Template - Read, Draw, Write worksheet, using the model shown or creating your own. Note that the problems use mixed operations and have two steps.
- Distribute that worksheet to your students and do the remaining problems together, answering questions along the way.
Independent working time(30 minutes)
- Distribute the Four in a Row Game - practise Two-Step Word Problems with Mixed Operations worksheet. Review the instructions.
- Put students in pairs and distribute the game board and set of questions to each pair.
- To verify the correctness of student answers while playing, you can either distribute the answer sheet for them to check each other or have students check with you (or another member of the class) who has the answers. Questions and answers are numbered.
- Make a guide with examples of different kinds of models to solve word problems (tape diagrams, number bonds, area models, number lines, etc.) and allow students to use it as a reference.
- Have students create more cards by writing additional two-step word problems using three-digit numbers.
- On the back of one of their sheets, have students solve one of the problems from the game, projected for all to see or written on the board. Demonstrate the solution and spot check student work for the accurate solution.
Review and closing(5 minutes)
- Discuss, "How might the RDW strategy be helpful when solving more challenging word problems?" Take student responses.
