Multiplication as Repeated Groups

Description

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.

Phases

# Phase Name Duration Description
1 Title card 3 s Title "Multiplication as Repeated Groups" fades in
2 3×4 intro label 2 s "3 groups of 4" text appears
3 Groups appear (3×4) 6 s Three colored groups of 4 dots pop in one group at a time
4 Grid rearrange (3×4) 4 s Dots animate into a 3×4 array; equation "3×4=12" shown
5 Clear & 2×5 intro 2 s Fade out; "2 groups of 5" text
6 Groups appear (2×5) 5 s Two groups of 5 dots appear
7 Grid rearrange (2×5) 4 s Dots form 2×5 array; equation "2×5=10" shown
8 Summary 4 s Both equations side-by-side; fade out
