I can fill in a blank cell in the 0-99 grid using the column and row patterns, without counting — Unit 7: The Tens & Ones Patterns in a Grid
I can say the decade words in order: twenty, thirty, forty, fifty, sixty, seventy, eighty, ninety
I can count through any decade using the pattern of the tens word staying the same while the ones count up
I know that when the ones reach nine, the next number moves to the next decade word in order
I can count all the way from zero to ninety-nine using this pattern
Success Criteria

Learning Sequence
I can write the decade words correctly, including the tricky spellings of forty and fifty
I can use a hyphen when writing numbers like forty-three, the same as I do for twenty-three
I can write the correct digits for a decade word, knowing that a decade like sixty means six tens and zero ones
Success Criteria

Learning Sequence
I can listen for the strong 'teen' ending and the soft 'ty' ending to tell two similar-sounding numbers apart
I can say pairs such as thirteen and thirty correctly, without mixing them up
I know that a teen number is close to ten, while its matching decade number is a whole number of tens
I can check an unsure number by saying it back or using the context to decide which one makes sense
Success Criteria
Lesson 3: Teen Ty Misconception
We are learning to tell the difference between the teen numbers and the decade numbers by listening for their ending.
