Arithmetic 123

Learn math at your own pace! 31 modules with explanations, examples and exercises. No ads, no internet needed. Made for primary school.

Arithmetic helps primary-school children learn math step by step. The app first explains the concept, then shows an example, and then lets the child practice on their own — just like in class.

FIRST UNDERSTAND, THEN PRACTICE Every module follows four phases: • Explanation — the concept is explained step by step with interactive screens • Example — a worked example to go through together • Practice — exercises with hints to help you on your way • Independent — exercises without hints, to show what you can do

31 MODULES, 4 SECTIONS Section 1 — Number sense Numbers up to 100,000, fractions, decimals, ratios, tables and charts, multiples and number patterns

Section 2 — Measurement Time, money, temperature, scale, length, volume and weight

Section 3 — Geometry Points and lines, angles, polygons, triangles, circles, symmetry, area and perimeter

Section 4 — Operations Addition, subtraction, multiplication, division, fraction arithmetic, calculation strategies, percentages, order of operations
