`Books 11, 12, 13 and 14 cover the 32 learning intentions for children in Year 4, aged about 8 to 9 years old.  At this level, children have begun to recognize that numbers can be treated as wholes or be partitioned (broken up) and recombined. This is called part-whole thinking. They can derive results from known facts, such as solving addition problems by using doubles or teens, e.g., 7 + 8: 7 + 7 = 14, so 7 + 8 = 15. They can recognize any number up to 1,000. They use hundreds, tens and ones for 3-digit problems. They can count forwards and backwards from 1,000 in ones, twos, threes, fives or tens. They should know their two, five and ten times tables and the matching division. They solve fractions by adding, e.g., ⅓ of 12 is 4 because 4 + 4 + 4 = 12. Get this 110-page activity book in PDF format immediately upon purchase.`
