Target 120: The Ultimate Number Line Game

Optimized for 2nd Grade Reveal Math (Unit 3) & CCSS 2.NBT.B.5

Are your students tired of worksheets? Bring math to life with Target 120! This high-energy floor or tabletop game is designed to build mental math fluency, mastery of 3-digit number structure, and the "Jump and Step" strategy.

Specifically tailored to supplement Reveal Math Grade 2 (Unit 3), this packet provides everything you need to move students from counting on fingers to confident mental addition and subtraction within 120.

What’s Included in this 40+ Page Packet?

• Comprehensive Number Line (0-120): A clear, easy-to-read number line available in both vibrant color and ink-saving Black & White. Perfect for hallway floor paths or classroom desks!

• 4 Diverse Sets of Challenge Cards:

  • Set 1: Full Color (Clean & Bold)

  • Set 2: Color with Base-Ten Block Visuals (Scaffolded for learners)

  • Set 3: Black & White (Printer-friendly)

  • Set 4: Black & White with Base-Ten Block Visuals (Scaffolded)

• Student Strategy Log: An accountability recording sheet where students document their "Starting Number," "Challenge Card," and "Mathematical Strategy" (Jumps & Steps).

• Teacher Grading Rubric: A professional 4-point scale rubric to assess Strategy Application, Accuracy, and Mathematical Communication.

• Step-by-Step Instructions: Student-friendly guide with "Math Talk" prompts to foster independent play during centers.

Why Teachers Love It:

This isn't just a game—it's a formative assessment tool. By using the Strategy Log and the Base-Ten Visual Cards, you can instantly see which students are still counting by ones and which have mastered jumping by tens. The extension to 120 ensures students are prepared for the "Crossing 100" hurdle often found in late 2nd grade.

Perfect for:

• Math Centers & Stations

• Small Group Intervention (RTI)

• Morning Work

• Whole-Class Floor Games

Common Core Standards Aligned:

• 2.NBT.A.1: Understand that the three digits of a three-digit number represent amounts of hundreds, tens, and ones.

• 2.NBT.B.5: Fluently add and subtract within 100 using strategies based on place value, properties of operations, and/or the relationship between addition and subtraction.

• 2.NBT.B.9: Explain why addition and subtraction strategies work, using concrete models or drawings.

How to Use:

1. Print & Prep: Choose the card set that fits your students' needs (Visuals or Numbers only).

2. Set the Stage: Tape the number line to the floor for a "Life-Sized" game or keep it at a table for a small group.

3. Play: Students flip a card, move their token, and—most importantly—record their thinking on the Strategy Log.

4. Assess: Use the included rubric to grade their strategy logs and check for fluency.
