For children familiar with multiplication facts, multi-digit addition and subtraction, exact division, simple fractions and rectangles. Grade 3 learners can begin with Build and Reason. Revisit fraction operations, decimals/time and angles after the prerequisites have been taught. Grade 4 learners can use the full sequence and selected stretch problems. Try 20–30-minute sessions or shorter, with discussion and hints as needed.
