Create one continuous premium Grade 6 mathematics animation titled “What Makes a Number Prime?” Integrate visuals and narration together. Begin with arrays and factor pairs; reveal the terms only after learners see the patterns. Use accurate, readable numbers and give brief thinking pauses.
SEQUENCE 1 — ARRANGE 12
Visual: show 12 figs as a 1×12 row, 2×6 rectangle, 3×4 rectangle, then the rotated arrangements 4×3, 6×2 and 12×1 without counting rotated duplicates as new factor pairs. Display 12 = 1×12 = 2×6 = 3×4.
Narration: “Let’s arrange twelve figs into rectangles. We can make one row of twelve, two rows of six, or three rows of four. Each arrangement shows a factor pair of twelve.”
SEQUENCE 2 — ARRANGE 7
Visual: show 7 figs in a 1×7 row and 7×1 column. Try to form equal rows with 2, 3 or 4 in each row; show why they do not make a complete rectangle.
Narration: “Now try seven figs. We can make one row of seven, or seven rows of one. No other equal rectangular arrangement works.”
SEQUENCE 3 — COUNT FACTORS
Visual: FACTORS OF 12: 1, 2, 3, 4, 6, 12. FACTORS OF 7: 1, 7.
Narration: “The row and column numbers are factors. Twelve has more than two factors. Seven has exactly two: one and seven.”
SEQUENCE 4 — NAME THE PATTERN
Visual: reveal PRIME NUMBER: exactly two factors, 1 and itself. COMPOSITE NUMBER: more than two factors. Show 7 → PRIME; 12 → COMPOSITE. Then show examples: primes 2, 3, 5, 7, 11, 13; composites 4, 6, 8, 9, 10, 12.
Narration: “A number with exactly two factors—one and itself—is called a prime number. A number with more than two factors is called a composite number.”
SEQUENCE 5 — WHAT ABOUT 1?
Visual: show 1 as a single dot. Display FACTORS OF 1: 1. Place it outside the PRIME and COMPOSITE groups.
Narration: “One has only one factor: itself. So one is neither prime nor composite.”
SEQUENCE 6 — QUICK THINK
Visual: ask “Prime or composite?” for 5, 9, 11 and 15. Pause, then reveal 5 prime; 9 composite; 11 prime; 15 composite.
Narration: “Pause and decide: prime or composite? Check how many factors each number has. Five and eleven are prime. Nine and fifteen are composite.”
End memory card: “Prime = exactly 2 factors. Composite = more than 2 factors. 1 = neither.” Do not introduce prime factorisation.
