Slide Deck

Fluency Frenzy: Add & Subtract!

Let's become Addition and Subtraction Superstars!

Welcome students and introduce the day's objective: to sharpen our addition and subtraction skills. Start with a quick warm-up to get their brains thinking.

Warm-Up: Number Talk

What's the answer? How did you get it?

Problem: 34 + 28 = ?

Display a simple problem and ask students to solve it mentally, then share their strategies. This activates prior knowledge and encourages different approaches. Example: 25 + 17 or 50 - 18.

Quick Strategies Review

Think Fast, Solve Smart!

  • Counting On/Back
  • Breaking Apart Numbers
  • Using a Number Line

Remember: Accuracy first, then speed!

Briefly review key strategies like counting on, breaking apart numbers (e.g., 345 + 123 = 300+100 + 40+20 + 5+3), or using a number line. Emphasize that speed comes with practice, but accuracy is always the top priority.

Independent Practice: Worksheet Time!

Time to show what you know!

Complete the problems on your Fluency Frenzy Worksheet.

Focus on:

  • Solving accurately
  • Showing your work

Explain that students will now work on a worksheet to practice these skills independently. Distribute the Fluency Frenzy Worksheet. Remind them to show their work and to ask for help if they need it. Circulate around the room to provide support.

Cool-Down: How Do You Feel?

Thumbs Up: I feel confident!
Thumbs Sideways: I'm getting there!
Thumbs Down: I need more help!

Conclude the lesson with a quick check-in. This allows students to self-assess and provides the teacher with immediate feedback on student understanding. Collect the worksheets.
