RightStart™ Mathematics Level E
RightStart™ Mathematics Level E deepens work with fractions and introduces decimals and multi-digit operations. Students continue to use visualization and the abacus to build conceptual understanding.
What RightStart™ Mathematics Level E Covers
- Numeration: primes, factors, and numbers to the billions
- Multi-digit addition, subtraction, and 2-digit multiplication
- Division facts with remainders and short division
- Fractions: add, subtract, compare, and multiply by a whole number
- Decimals and simple percents to two places
- Measurement: perimeter, area, and unit conversion
- Geometry: symmetry, angles, and classifying shapes
