Adding two single-digit numbers
Children add pairs of one-digit numbers, with a number line from 0 to 18 across the top of page 1 to start at the bigger number and hop forward. Picture problems and a row of doubles, such as 6 + 6 and 9 + 9, come first. Ten of the 15 facts on page 2 cross 10, like 9 + 4 and 8 + 6, which is where counting on gets slow and making ten helps. The key ends with one worked example of each strategy.

Teaching tips
1
For 2 + 9, a student who counts on from 2 makes nine hops. Point to the number line direction: start at 9 instead and hop just twice.
2
For facts like 9 + 4, use the key's make-ten move: take 1 from the 4 to turn the 9 into a ten, so 9 + 4 is the same as 10 + 3.

Differentiation

Ways to adjust the picture problems and facts for different students.
Support
Count and hop
- Do the three picture problems with real counters before students write the total.
- Have students put a finger on the number line and hop for every page 2 fact.
- Start page 2 with the five facts that stay under 10, such as 7 + 2 and 6 + 3.
On level
Teach as written
- Both pages, picture problems first.
- Students circle the page 2 facts they solved by making ten.
Extension
Beyond doubles
- Use each doubles answer to solve a near double, like 6 + 7 from 6 + 6.
- Write three other pairs of single-digit numbers that make 13.
Curriculum alignment.
Each one is checked against the official document. Where the resource covers only part of a standard, the note says so.
Australian Curriculum: Mathematics · Year 1
AC9M1N04Add within 20 using strategies
Students add single-digit numbers with sums up to 18 by counting on along a number line, adding picture groups, using doubles and making ten; subtraction and physical materials are not part of the sheet.
Good to know.
How is it different from the Maths Addition Worksheet?
Every problem here adds two single-digit numbers. The Maths Addition Worksheet starts with facts to 20 and moves on to two-digit sums with regrouping.
