Step 7 Number

READ & WRITE any decimal, fraction, ratio, percentage or integer

COUNT in DECIMALS - thousandths, hundredths, tenths, ones and tens forwards and backwards etc.

Say the NUMBER 1/1000th, 1/100th, 1/10th BEFORE or AFTER any number

ORDER DECIMALS to 3 decimal places

ORDER MIXED FRACTIONS with 1/2s 1/3s 1/4s 1/5s 1/10s

ROUND decimals to the NEAREST WHOLE NUMBER

ROUND whole no's & decimals to NEAREST 1 or 1/10

ROUND decimals to the NEAREST 100, 10, 1, 0.1 or 0.01

Instantly recall ALL x and ÷ facts to 10 x 10

Know EQUIVALENT FRACTIONS with denominators of 10, 100, 1000

Recall CONVERSIONS between fractions, decimals & percentages for 1/2, 1/3, 1/4, 1/5, 1/10

Know SQUARES and SQUARE ROOTS to 100

Know FACTORS of numbers to 100

Know HOW MANY 10s, 100s & 1000s in numbers to a million
