__Multiplication using the Split Strategy__Automatically recall multiplication tables to 10x10. Automatically calculate multiplications beyond 10x10 by multiplying numbers in parts.

Eg. 312x6=? This can be thought of as 300x6 + 10x6 + 2x6 = 1800+60+12 = 1872

*Split Strategy Game*

Roll a die twice to make a 2-digit number. Roll a third time to create a multiplying number. Use the split strategy to multiply quickly in your head. For a challenge, roll the die to make a 3 or 4-digit number and calculate the multiplication.

__Associative Law__When adding or multiplying, you can rearrange the numbers in a different order, so that

(a+b)+c = a+(b+c) and (axb)xc = ax(bxc). Eg. (6+3)+4 = 6+(3+4) and (2x4)x3 = 2x(4x3).

The associative law does NOT work for subtraction or division.

__Distributive Law__When adding, subtracting or multiplying, numbers can be ‘distributed’ across so that ax(b+c) = axb+axc. Eg. 3x(2+4) = 3x2+3x4. 3 lots of (2+4) is the same as 3 lots of 2, plus 3 lots of 4, so the 3x can be ‘distributed’ across the 2+4, into 3x2 and 3x4. This can be extended to larger numbers. Eg. 6x204 becomes 6x200+6x4 = 1200+24 = 1224. The distributive law does NOT work for division.

__Square Numbers__Automatically recall square numbers Eg. 1x1=1, 2x2=4, 3x3=9, 4x4=16

__Highest Common Factor__Recognise and articulate the association between multiplication and division. Automatically calculate the highest common factor of 2 numbers (the highest number that divides exactly into two or more numbers). Eg. Highest common factor of 12 and 16? The factors of 12 are: 1,2,3,4,6,12. The factors of 16 are: 1,2,4,8,16. The common factors of each are: 1,2,4 so 4 is the highest common factor.

__Lowest Common Multiple__Automatically calculate the lowest common multiple of 2 numbers (the smallest positive number that is a multiple of two or more numbers). Eg. Least common multiple of 3 and 5? The multiples of 3 are: 3,6,9,12,15,18 and the multiples of 5 are: 5,10,15,20. 15 is a common multiple of 3 and 5, and is the smallest (least) common multiple.

__Equivalence__Automatically recall common equivalent rates expressed as fractions, decimals and percentages. Eg. 10/100 = 0.1 = 10%; 25/100 = 0.25 = 25%; 50/100 = 50%; 75/100 = 0.75 = 75%; 100/100 = 1.0 = 100%

__Fractions__Automatically convert a given fraction to an equivalent fraction using related denominators. For instance, 1/6 = ?/12
