KS2 SATs Arithmetic: Percentages of Amounts
Find any percentage of an amount from three building blocks: 10% (divide by 10), 5% (half of 10%) and 1% (divide by 100). Pip the panda finds 15% of 240 (36), learns the trap of confusing 1% with 10%, then you find 35% of 360 in a SATs-style arithmetic question.

Bruno the bear works out 1,624 ÷ 14 with long division: write the 14 times table down the side, then divide, multiply, subtract and bring down, one digit at a time, to get 116. Then try 2,592 ÷ 24 yourself and learn the zero trap. A regular KS2 SATs arithmetic paper question.

To work out 2.6 × 3, Momo the monkey ignores the decimal point (26 × 3 = 78), then puts it back with the same number of decimal places: 7.8. Learn to check with an estimate, then work out 3.25 × 4 yourself. A favourite KS2 SATs arithmetic paper question.
2:22KS2 SATs Arithmetic: Multiplying and Dividing Fractions by Whole Numbers
To multiply a fraction by a whole number, multiply the numerator: 3/5 × 4 = 12/5 = 2 2/5. To divide a fraction by a whole number, multiply the denominator: 3/4 ÷ 3 = 3/12 = 1/4. Pip the panda shows both with fraction bars, then you work out 2/3 ÷ 4 yourself.
