🍫 Snap the Bar
Why is 1/2 the same as 0.5?
The fraction has a 2 in it. The decimal has a 5. So shouldn’t a half be 0.2? Let’s snap a chocolate bar into 10 squares and find out what the digit after the point really counts.
Start snapping ↓Ten squares. One seat after the point.
Press Next step. The bar is one whole.

“1/2 has a 2 on the bottom, so it’s 0.2!”
The digit after the point counts tenths.
Half the bar is 5 tenths, so 1/2 = 0.5.
Half the bar is 5 tenths, so 1/2 = 0.5.
Tap a square to snap off that many. Tap the first one again to start over.
Your turn: 5 tenths challenges
Same bar, same ten squares. Can you name every piece both ways, and dodge the trap?

Half the baris 5 squares:
1/2 = 5/10 = 0.5
1/2 = 5/10 = 0.5
A fifthis 2 squares:
1/5 = 2/10 = 0.2
1/5 = 2/10 = 0.2
To turn a fraction into a decimal, don’t copy its digits. Ask one question: how many tenths is it? Then write that number after the point. 3/10 is 0.3, 1/2 is 0.5, and 13/10 is a whole bar and 3 squares: 1.3.
