Counting, partitioning and calculating.
· Children count on and back from any two-digit number in steps of 1, 2, 5 and 10.
· Children count a large set of objects efficiently, for example grouping them into twos, fives or tens. They understand that it is more reliable, and can be quicker, to group the objects rather than count them in ones. They solve problems involving counting such as:
How many 2p coins are needed to make 12p?
· Count on in tens from the number 27. Will the number 85 be in the count? How do you know?
Children explain their reasoning and use equipment or images such as a 100-square to support their explanations.
· Children read and write two-digit and three-digit numbers, recognising the difference between, for example, 'fifty' and 'fifteen'. They know what each digit in a two-digit and three-digit number represents.Click here for a good website to practice this.
· Children order numbers and know that when they order two-digit numbers the tens digit is more significant than the units digit.
· Children partition two and three-digit numbers and use this to solve problems. For example, they show that 53 50 3 or 40 13 or 30 23, and so on.
· Children add or subtract a one-digit number to or from any two-digit number by counting in ones, taking particular care when counting over a tens boundary
