The purpose of this unit is to build and consolidate the addition and subtraction facts to ten. These addition and subtraction facts are building blocks for part-whole thinking.
form addition facts to ten using dot patterns on a quinary frame.
form subtraction facts to ten using dot patterns on a quinary frame.
Advanced Counting (Counting-On).
Pre-requisite knowledge / skills: recognising and describing patterns to ten on pre-made cards
Quinary Tens Frames
Teacher holds up a tens frame and asks
Tell me the number pattern?
How many gaps are there?
Teacher then states the appropriate number sentence e.g. 6 and 4 is 10.
Repeat several times with all cards to build facts to ten.
Teacher holds up a tens frame and asks
Who can tell me the number sentence for this card?
Repeat several times, ensuring that all cards (0-10) have been covered up to this point.
Teacher models the recording of the number sentences as “6 and 4 is ten”, then “6+4=10”
Teacher explains to students that today
We are using the cards to work on take-away equations starting with ten.
Teacher holds up a tens frame and asks
How many dots could I fit on this frame?
How many have gone?
How many are left?
Who can give me a number sentence for this card?
If necessary the teacher gives the appropriate number sentence e.g. 10 take away 6 is 4
Repeat several times with all cards to build facts to ten.
Teacher gives the number sentence and asks the students to find the appropriate card. For example:
I had ten dots and I took away 6, how many do I have left? Can you find the card for that? How many are left?
Teacher models the recording of the number sentences as “10 take away 6 is 4”, then “10 - 6 = 4”.
Notes:
There are many ways to record the work being done and what is appropriate depends on the students in the group. Options include:
