Year 2 Adding Two 2-Digit Numbers Differentiated Worksheets and Answers

➕ Build confidence when adding two 2-digit numbers

Give pupils focused addition practice with this differentiated Year 2 maths worksheet set. It provides three carefully graduated levels, allowing children to begin with additions that do not cross a ten before progressing to regrouping and calculations with larger totals.

Clear answer boxes provide plenty of room for pupils to record each total. Children can use a number line or the included 1–100 number square for additional support.

🔺 Triangle – Developing Confidence

The Triangle worksheet contains additions that do not require pupils to cross into the next ten. These calculations provide an accessible starting point for children developing their understanding of place value and two-digit addition.

⭕ Circle – Crossing a Ten

The Circle worksheet introduces calculations in which the ones digits combine to make more than ten. Pupils must bridge or regroup across a tens boundary while working with totals below 100.

⬜ Square – Greater Challenge

The Square worksheet uses larger two-digit numbers and more demanding regrouping calculations. Most totals are close to 100, with three calculations extending slightly beyond 100 to 103 and 104.
