Addition and Subtraction Within 10 000
Add and subtract numbers up to 4 digits in columns, renaming where needed, and calculate mentally with 2-digit numbers.
Your child adds and subtracts numbers up to 4 digits in columns, starting with the ones and renaming whenever a place has 10 or more, or not enough. Subtracting from numbers such as 5006 means renaming across zeros. Your child also adds and subtracts two 2-digit numbers mentally, and works backwards through a story to find how many there were at first. Read the study guide →
About this chapter
Primary 3 addition and subtraction questions work with numbers up to 10 000: adding in columns with renaming, subtracting across zeros, adding and subtracting two 2-digit numbers mentally, and word problems about totals, differences and how many there were at first. A mixed practice set at the end brings the four together.
Practise by question type: adding 4-digit numbers questions, subtracting across zeros questions, mental addition and subtraction questions, how many at first word problems and P3 addition and subtraction mixed practice questions.
