• I can say and write the number 100 as the number after ninety-nine

• I can count forwards from a given number past one hundred, up to one hundred and twenty

• I can count backwards from a given number in the hundreds down towards one hundred

• I can say the number that comes just before or just after a given number past one hundred

• I can fill in a missing number in a sequence, whether counting forwards or backwards

Success Criteria

Lesson 1: Counting Sequence

We are learning to count forwards and backwards past one hundred to one hundred and twenty.

• I can read a number past one hundred and write its digits

• I can write the words for a number past one hundred, such as one hundred and fourteen

• I can write the words for the number that comes next after a given number past one hundred

Success Criteria

Lesson 2: Digits & Words

We are learning to read and write the words for numbers from one hundred to one hundred and twenty.

• I can group a large collection into tens and count the groups

• I can count on from one hundred using groups of ten and any leftover ones

• I can state the total of a collection that is more than one hundred

• I can count a collection accurately without recounting from the start

Success Criteria

Lesson 3: Counting Collections

We are learning to count a large collection of more than one hundred objects by grouping it into tens.

• I can build a number line from zero to one hundred and twenty using intervals of ten

• I know that marking every single number is impractical for a line this long, so I use larger intervals

• I can build a number line for a smaller range within one hundred to one hundred and twenty, using a suitable interval

• I can estimate where a given number would sit on a number line based on the landmarks shown

Success Criteria

Lesson 4: Building the Number Line to 120

We are learning to build and read a number line that extends past one hundred to one hundred and twenty.

• I can read the two end numbers on a number line before I place anything on it

• I can estimate where a number belongs on a line that shows only its two end values

• I can place the same number on two lines with different end values and explain why it lands in a different spot

• I know that fifty sits in the middle of a line ending at one hundred, but before the middle on a line ending at one hundred and twenty

Success Criteria

Lesson 5: Magnitude to 120

We are learning that where a number sits on a number line depends on the two numbers at the ends of that line.

• I can read the numbers that a group of MAB blocks represents, including a hundred flat

• I can build a number past one hundred using MAB hundreds, tens and ones

• I can convert an amount made with hundreds and tens into the equivalent number of tens alone

• I can convert an amount made with hundreds and tens into the equivalent number of ones alone

Success Criteria

Lesson 6: Using MAB up to 120

We are learning to represent numbers past one hundred using MAB hundreds, tens and ones.
