Free Picture Subtraction Up to 20 Worksheets

Once students are comfortable with numbers within 10, it is time for the big challenge: Subtraction within 20. This is the bridge to Grade 1 math.

Counting 18 or 19 objects can be messy. That is why our picture subtraction up to 20 worksheets use organized visuals—like Ten Frames and neat rows—to help children see the structure of numbers (Place Value) while subtracting.

Why Visuals Matter for Numbers 11-20

Subtracting double-digit numbers can be intimidating. Visuals make it manageable:

1. Grouping: Seeing a group of 10 and some extras helps them understand “Teen Numbers” (10 + 4 = 14).
2. Accuracy: Crossing out items in a structured row reduces counting errors compared to scattered pictures.
3. Preparation: This is the final step before moving to picture subtraction for grade 1, where word problems begin.
