Represent the structure of groups of ten in whole numbers
Recognise that ten ones is the same as one ten
Use 10 as a reference in forming numbers from 11 to 20
Count large sets of objects by systematically grouping in tens
Partition two-digit numbers to show quantity values
Use number lines and number charts to assist with locating the nearest ten to a number
Estimate, to the nearest ten, the number of objects in a collection and check by counting in groups of ten (Reasons about quantity)
Balls or bean bags
Hoops or buckets
Whiteboards and markers
Activity set-up
Setup balls or bean bags in a central area.
One player from each pair runs to a central point, collects a ball and runs it back to their base, where they tag a team-mate who does the same. The aim is to collect the most balls, before organising and describing the collection.
Teams collect as many balls as possible in the allotted time (e.g. 60 seconds).
When all the balls have been removed from the centre, the coach calls ‘STOP!’
Have students organise and describe their collection.
Guide students to reorganise and describe their collection as many times as they can within the next 5 minutes.
Have students draw and record all of their ways of thinking about their collection.
Take more than one ball at a time.
Vary the movement – try springing from 2 feet. You may need to reduce the time for collecting (e.g. 30 seconds).
Vary the method of transporting the ball – use legs to hold the ball, carry the ball under the armpit, hold the ball above the head.
