Number Line Zoom

Use place value to plot multi-digit numbers on a number line.
  • Apply place value to locate numbers on number lines from 0 to 1 million.
  • Number lines show numbers of the largest place value, clicking between numbers zooms in to show the next place value.
  • Levels begin with 4-digit numbers, then advance to 6-digit numbers.

Lines of Symmetry

Find lines of symmetry that fold shapes into congruent halves.
  • Develop concept and language for lines of symmetry.
  • Find the line of symmetry for polygons.
  • Levels begin with finding one line of symmetry, then advance to finding multiple lines of symmetry for a given shape.

JiJi Cycle - Fraction Addition and Subtraction

Estimate fraction sums and differences
  • Use visual fraction models to estimate sums and differences on number lines.
  • Levels begin with visual models, then progress to fraction notation.

Fraction Addition and Subtraction

Add and subtract fractions with like denominators
  • Use number lines to model fraction sums and differences.
  • Add and subtract fractions and mixed numbers.
  • Feedback shows visual models proof of sums and differences.

Creatures and Boots Problem Solving

Solve multi-step problems involving multiple operations
  • Develop problem solving strategies for finding combinations of creatures and boots.
  • Levels begin with finding the number of boots for a given combination of creatures, then advance to finding combinations of creatures given a set of boots.
  • Problems begin with visual models and transition to visual-symbolic models.

Blast Pad Number Lines

Apply concepts of unit fractions and multiplication to number lines.
  • Estimate fractions >1 and whole numbers using unit fractions on a number line.
  • Estimate products of whole numbers and fractions on a number line.
  • Visual feedback models multiplication of fractions as iteration of unit fractions.
