Gone Fishing: Equations
Students will understand the meaning of the equal sign. Students will be able to determine whether equations involving addition and subtraction are true or false.
- Remind students the meaning of the Less than(smaller), Greater than(bigger), and Equal to(same) symbols in numerical sentences. Explain that the value of both sides of the number sentence must be correctly represented by the symbol.
- Have your students read number sentences as they would read a sentence in a book. For example, 1 + 1 = 2.Explain that this is true because the value of both sides is the same. Tell your students that the example 1 + 1 > 2Is not true.
- Tell your students that they will be working to find the right symbol to make sure the number sentences are true.
Explicit Instruction/Teacher modeling(5 minutes)
- Review with students, through simple examples, numerical sentences that practise these symbols. Examples used might be: 6 - 1 < 7, 6 - 1 > 4And 6 - 1 = 5.
Guided practise(10 minutes)
- Play Less Than or Greater Than: 1 to 20With your students, explaining what true and false statements are.
Independent working time(10 minutes)
- Pass out worksheets to your students based on skill level, and review the directions.
- Walk around the classroom, making sure that your students are following instructions and completing appropriate level worksheets.
- Enrichment:Give students more challenging worksheets from the workbook, such as mixed addition and subtraction worksheets.
- Support:Give students worksheets that are easier to complete.
- Direct your students to write an example of a number sentence that is true and a number sentence that is false in their maths journals.
- Have them label these examples “true” and “false” and explain why the sentences are true or false.
Review and closing(5 minutes)
- Quickly quiz students as a whole group with flash cards of true or false number sentences.
- Have students respond to true number sentences with a thumbs-ups or a thumbs-down.
