Meaning of 50%
100% split into 2 equal shares
50% of 212
50% of 830
50% of 21

Build one share
Double-check
The half-split rule
Concrete · share 100 counters
100whole
→
Pictorial · two equal bar parts
Abstract · same idea in symbols
SPLIT ÷ 2
50/100 = 1/2
50% of n = n ÷ 2
Concrete · balance two shares
212→200+12
1006
106
first share
1006
106
second share
Pictorial · one bar, two equal halves
Abstract · halve each easy part
HALVE ÷ 2
212 ÷ 2 = 100 + 6 = 106
Concrete · split 830 into easy parts
830→800+30
40015
415
first share
40015
415
second share
Pictorial · the balanced bar
Abstract · the same divide-by-two move
HALVE ÷ 2
830 ÷ 2 = 400 + 15 = 415
Concrete · even the last 1 can split
21→20+1
100.5
10.5
first share
100.5
10.5
second share
Pictorial · both halves stay equal
Abstract · halve, then double-check
HALVE ÷ 2
21 ÷ 2 = 10 + 0.5 = 10.5
CHECK × 2
10.5 × 2 = 21
Concrete · choose two equal shares
642 → 600 + 42
Pictorial · build one half
Abstract · finish the half-split
Split both parts, then add.
Work on your whiteboardFind half of 600, half of 42, and then 50% of 642.Submitted — your balance receipt is ready.
Concrete · balance the two shares
642→600+42
30021
321
first share
30021
321
second share
Pictorial · 321 is exactly half
Abstract · calculate and check
HALVE ÷ 2
642 ÷ 2 = 300 + 21 = 321
CHECK × 2
321 × 2 = 642
50% = 321
½
You can always find 50%.
Make two equal shares. One share is the answer.
50% = 1/2Read fifty percent as half.
SplitBreak the whole into easy parts.
÷ 2Halve each part, then add.
× 2Double the answer to check.
