Number Sense Intervention

Build understanding of what numbers mean. The Number Sense Toolkit gives learners opportunities to see, build, compare, and explore numbers. Clear visual supports and structured practice help make early math concepts more approachable, with encouragement from Dareold the Turtle and Chester the Chameleon.

Explore eight skill areas:

• Bigger or Smaller: Compare quantities and numbers, explore distance, and use greater-than and less-than symbols.
• Build the Number: Connect tens and ones to the numbers they represent.
• Missing Numbers: Practice counting forward and backward and finding numbers before, after, and between.
• Number Bonds: Explore how parts join to make a whole.
• Number Lines: Locate numbers, compare their positions, and explore jumps and distance.
• Expanded Form: Break two-digit numbers into tens and ones.
• Subitizing: Recognize quantities through dots, dice, dominoes, and familiar patterns.
• Ten Frames: Organize quantities, compare amounts, and explore ways to make numbers.

Practice pages and tools—including a Bond Builder, Jump Mat, Dot Builder, and ten frames—offer different ways to explore concepts.

Use counters or other small objects alongside the book when hands-on support helps.

Worked solutions that help teach

Answer keys follow each practice section so learners can check their thinking while the skill is still fresh. Completed visual models and answers help children compare their work, notice where a mistake may have happened, and try again with support.

Open-ended activities allow for more than one correct response.

Use at the learner’s pace

Begin where the learner feels successful.
Work through one skill at a time, revisit helpful activities, and allow space to talk, build, draw, or count. There is no need to complete every page in order.

Use at home, in the classroom, or during individual math support.
