Unit 9: Understanding Tens & Ones
Year 1
Students need this knowledge first
I can describe an amount using tens frames as 'ten and ___', and connect it to the verbal number and written digit to 20 — Unit 9: Progressing to 20
I can count using the tens-and-ones pattern through every decade, and know that a decade word like sixty means six tens and zero ones — Unit 8: Counting to 99
I can count out ten items and bundle them together to make one group of ten
I know that one bundle looks like one thing but is worth ten
I can count a collection by stating how many bundles and how many loose ones there are, then say the total
I know that bundling does not change how many items there are, it just makes them quicker to count and easier to keep track of
Success Criteria
Lesson 1: Using Bundles to Make Tens
We are learning to group a collection into tens by bundling ten items together, with any leftovers staying loose.
Learning Intention
Learning Sequence
I can recognise that counting a large collection one by one makes it easy to lose track
I can push a variety of items together into groups of ten, leaving any leftovers loose
I can count the groups of ten and then count on the loose ones to find the total
I know that counting by groups of ten is faster and more reliable than counting one by one
Success Criteria
Lesson 2: Counting Collections with Tens
We are learning to count a large collection accurately by grouping it into tens rather than counting one by one.
Learning Intention
Learning Sequence
I know that a MAB one block is worth one, the same as a counter or a stick
I can group MAB ones into tens by pushing them together, leaving any leftovers loose
I can count the groups of ten and then the loose ones to find the total
I can make a new group of ten when my loose ones reach ten
Success Criteria
Lesson 3: Using MAB Ones
We are learning to group MAB one blocks into tens, the same way as with other materials.
Learning Intention
Learning Sequence
I can show that a tens rod is the same as ten MAB ones lined up together
I know that ten loose ones can be traded for one tens rod
I can count a collection of tens rods by tens, such as three rods is thirty
I can read a mixed collection of tens rods and ones by counting the rods first, then counting on the ones
Success Criteria
Lesson 4: Understanding the MAB Tens Rod
We are learning that a MAB tens rod is worth ten ones already joined together.
