What a brilliant site you have!!! I love it, especially as it saves me hours and hours of hard work. Others who haven't found your site yet don't know what they are missing!
Number and place value
ACMNA055 – Recall addition facts for single-digit numbers and related subtraction facts to develop increasingly efficient mental strategies for computation
Samples: Adding three numbers. Add three numbers - each under 6. Adding three single digit numbers.
4.NA.3 – Create and continue spatial patterns and number patterns based on repeated addition or subtraction.
Samples: Add single digit numbers. Addition to 20. Counting Forwards By 10. Make 10. Single digit addition (missing number).
5.NA.3 – Describe spatial and number patterns, using rules that involve spatial features, repeated addition or subtraction, and simple multiplication.
Samples: Single Digit Addition Match. Place value - 'Adding On' single digit numbers.
5.NA.1 – Apply additive and simple multiplicative strategies and knowledge of symmetry to:
5.NA.1.a – Combine or partition whole numbers
Samples: Reading numbers – to 10,000. Write numbers – to 10,000. Comparing numbers – to 10,000.
KS2.Y3.N.AS – Number - addition and subtraction
Pupils should be taught to:
KS2.Y3.N.AS.4 – Solve problems, including missing number problems, using number facts, place value, and more complex addition and subtraction
Samples: Two digit addition. Challenge Puzzle - Addition Pyramid. Addition two Digit - Missing Numbers. Make 100.
3.OA.8 – Solve two-step word problems using the four operations. Represent these problems using equations with a letter standing for the unknown quantity. Assess the reasonableness of answers using mental computation and estimation strategies including rounding. (This standard is limited to problems posed with whole numbers and having whole-number answers; students should know how to perform operations in the conventional order when there are no parentheses to specify a particular order.)
Samples: Subtraction (two steps) - 1. Represent problems using algebraic equation. Problem solving: Two step - Activity 1.
