Basic facts: Blue = already known. Red = new strategies
Using a memorising strategy such as the multiplication chart shown on the fact sheet.
A strategy to help figure out timetables: that if you use your 10 times tables that you can figure out your 9 times tables. for example 8 x 10 = 80. 80-8 = 72 which =9x8
a strategy to answer 5 x 16 can be figured out by 5 x 10 =50 & 5 x 6 = 30 and then adding them together to =80
That 3x4 and 4x3 are different problems.
Stratergy:Unknown facts and doubling
Partitioning: 7x9 can also be 5x9 + 2x9 = 63.
Halving:5 if you half 10x6 this = 30 which is 5x6
that 4 to the power of 2 means that it is 4x4= 16
Didnt think that the reason why square numbers are called square numbers because they make a square! Makes sense now that i think about it.
Playing games are educational and beneficial
The importance of playing games such as snakes and ladders for number knowledge up to 100, using die to help with addition and where to move up to.
monopoly and the addition that comes with the money side of the game.
Card games and the scoring.
The same can be done with subtraction. 15-7=8. 15-5=10-2=8.
Strategy for addition(Bridging through 10): 7+5= 12. 7+3=10. whats left over is 2. Add 10+2=12.
The concept of one facts and two facts in relation to subtraction.
Contextualising division: Great way to explain division which I never thought of before 'But 1 (box)/lot of five apples means I only have 5 apples'
Using multiplication to help divide. 3x4=12 12/4 =3.
Sqaure roots and multiplication
Cant change the order of the equation for division as it does not make sense
Great way of explaining is through contextualising.
4/2 and 2/4 4 apples can be split with 2 people but 2 apples cannot be split with 4 people (uness cut in half).
