Year 7 - Number and Algebra
Standard 7.OA.1.1 - Add and subtract integers with word problems.
Included Skills: Algebra, Mixed Equations
Number and place value • Investigate index notation and represent whole numbers as products of powers of prime numbers - defining and comparing prime and composite numbers and explaining the difference between them - applying knowledge of factors to strategies for expressing whole numbers as products of powers of prime factors, such as repeated division by prime factors or creating factor trees - solving problems involving lowest common multiples and greatest common divisors (highest common factors) for pairs of whole numbers by comparing their prime factorisation • Investigate and use square roots of perfect square numbers - investigating square numbers such as 25 and 36 and developing square-root notation - investigating between which two whole numbers a square root lies • Apply the associative, commutative and distributive laws to aid mental and written computation - understanding that arithmetic laws are powerful ways of describing and simplifying calculations • Compare, order, add and subtract integers
