Missing Numbers: Math Review
Students will be able to identify missing numbers in an equation.
- Explain to the students that today they will be reviewing their math facts while completing fun puzzles.
- Ask the students to stand next to their desk for a brain warm up exercise.
- Play a quick game of Math Around the World: a game in which two students stand at a desk, and the caller (usually the teacher) gives them a math question. The student who answers correctly and with the fastest time moves to the next desk, and the student with the incorrect or slowest answer sits down.
Explicit Instruction/Teacher Modeling(10 minutes)
- Project or draw the first worksheet on the board.
- Read the instructions to the class.
- Activate prior knowledge by asking questions about the worksheet. Good examples include: Each row and column is a math equation. Who can tell me what an equation is? and It says to Multiply and Divide before adding and subtracting. Can anyone tell me why?
- Discuss the first puzzle equation as a class. Explain your thought process aloud as you write.
Guided Practice/Interactive Modeling(20 minutes)
- Ask students to complete the puzzle and worksheet in one of two ways:
- Continue asking questions and filling the puzzle in yourself, allowing students to give their thoughts.
- Have each student come up to the board and fill in the next blank number space, then defend and discuss their response with their peers.
Independent Working Time(30 minutes)
- Pass out the other worksheets and ask students to complete these on their own.
- Enrichment: For advanced students, allow them to do more difficult missing number worksheets and possibly branch out into Sudoku or Ken Ken puzzles.
- Support: For students in need of support, allow them to work in small groups to complete the worksheets. Students in need of support can also greatly benefit from one-on-one working time with the teacher or with an advanced student for peer tutoring.
- Student participation can be a quick form of active assessment.
- Students will turn in worksheets to be graded for assessment.
Review and Closing(10 minutes)
- See if any students have questions about the activity.
- Ask reflection questions. Examples include: Did anyone discover something about equations while working on this activity? Do you use math outside of class?
