Introduces negative numbers by showing a number line from -10 to +10 and demonstrating that numbers extend to the left of zero. Students see that negative and positive numbers are mirror images, then practice addition and subtraction using animated hops.
Animates factor trees for 60 and 84, showing how any composite number can be broken down into a unique product of prime numbers. Prime numbers are highlighted in distinct colors and the final exponential form is displayed with MathTex.
Show a number line from 0 to 20 with a colorful arrow hopping right for addition and left for subtraction. Two worked examples are shown: 5+3=8 (three hops right) and 8-3=5 (three hops left). Each hop is animated individually with equation labels updating live.
A visual introduction to counting for primary school students (ages 6–11), using animated dot groups on a number line to build number sense and subitizing skills. The animation shows dots appearing in groups, connecting visual quantity to numerals 1–10.
Demonstrates multiplication as repeated equal groups using colored dot arrays. Two examples are shown: 3×4 (three groups of four) and 2×5 (two groups of five). Groups appear one at a time, then dots rearrange into a neat grid with the equation label.
Introduces the concept of place value using visual blocks. A single small square represents 1 (ones), a row of 10 squares represents 10 (tens), and a 10×10 grid represents 100 (hundreds). The number 234 is built step-by-step.
