• I can identify the major markers on a 0-100 number line, such as the dark marks at each ten

• I can use the tens digit to find the right decade section of the line, then count on with the ones digit

• I can mark a given number on the number line using its tens and ones

• I can read off the number a marked point represents using the nearest ten and the ones remaining

Success Criteria

Lesson 1: Finding Tens & Ones on a Number Line

We are learning to locate a two-digit number on a 0-100 number line using its tens and ones.

• I can add two multiples of ten by adding the tens digits and keeping the ones digit at zero

• I can subtract one multiple of ten from another using the same idea

• I can add a multiple of ten to a two-digit number by changing only the tens digit

• I can subtract a multiple of ten from a two-digit number by changing only the tens digit

Success Criteria

Lesson 2: Addition & Subtraction Using Place Values

We are learning to add and subtract multiples of ten quickly by working with the tens digit alone.

• I can list the tens from 0 to 100 and say which two tens a given number sits between

• I can decide which of those two tens a number is closer to

• I know that a number exactly halfway between two tens rounds up to the higher ten

• I can round a two-digit number to the nearest ten

Success Criteria

Lesson 3: Rounding to the Nearest Ten

We are learning to round a number to the nearest ten by finding which ten it is closest to.

• I can identify which of two numbers is smaller and which is larger

• I can choose the correct sign, less than, greater than or equals, to compare two numbers

• I can find a missing number that makes a comparison true

• I can compare numbers given as expressions, such as tens and ones combinations, before choosing the sign

Success Criteria

Lesson 4: Greater Than Less Than Sign with Tens & Ones

We are learning to compare two numbers using the greater than, less than and equals signs.
