Digit word problems are common in Algebra curriculum. Students sometimes struggle to find the number due to difficulty in translating the words into equations. This card sort provides extra practice in matching words to equations to graphs and then to solutions.
The card sort provides practice related to these Common Core State Standards:
• CCSS.Math.Content.HSA-CED.A.2 Create equations in two or more variables to represent relationships between quantities; graph equations on coordinate axes with labels and scales.
• CCSS.Math.Content.HSA-CED.A.3 Represent constraints by equations or inequalities, and by systems of equations and/or inequalities, and interpret solutions as viable or nonviable options in a modeling context.
• CCSS.Math.Content.HSA-REI.C.5 Prove that, given a system of two equations in two variables, replacing one equation by the sum of that equation and a multiple of the other produces a system with the same solutions.
• CCSS.Math.Content.HSA-REI.C.6 Solve systems of linear equations exactly and approximately (e.g., with graphs), focusing on pairs of linear equations in two variables.
• CCSS.Math.Content.HSA-REI.D.10 Understand that the graph of an equation in two variables is the set of all its solutions plotted in the coordinate plane, often forming a curve (which could be a line).
1. Label the slides with numbers or letters. Post them around the room; ask students to find the sets that match.
2. Print the slides using the handouts feature – 4 or 6 slides to a page. Cut out the cards, and match sets.
3. After students match these cards, have each group create their own. Use the student created cards for extra practice. Or use the card sort for formative assessments.
