In practical activities and discussion, begin to use the vocabulary involved in adding and subtracting. To find one more or one less than a number from 1 to 10. To begin to relate addition to combining two groups of objects, and subtraction to ‘taking away’. Make your child aware of numbers in their environment. eg. ages, house numbers, car registrations, telephone numbers. Count as part of your everyday life. eg. stairs as you go up to bed, apples in the fruit bowl, cakes on a plate, spoons on the table. Practical one to one counting activities. eg. count the red Smarties, children around a table, birds in the picture. Recognise digits from 1 to 10 and match to a set of objects. Count out 4 objects. What is one more/one less? Development of addition and subtraction through practical activities. 5+3= Count out 5 counters and 3 counters. Then count how many altogether using one to one counting. OOOOO + OOO = OOOOOOOO 12345 123 12345678 Count out 5 counters and 3 counters. Then count on from 5. OOOOO + OOO = 8 678 5–3= Count out 5 counters and take away 3, leaves 2 left.
