Compare objects
Today I will: compare two groups of tens and ones.
Words to compare
- greater than >more36 is greater than 29.
- less than <fewer29 is less than 36.
- equal to =the same36 is equal to 36.
Look at the tens first.
3 tens is more than 2 tens.
36 is greater than 29.
Write the missing phrase. Use greater than, less than or equal to.
Compare numbers
Today I will: compare numbers. Tens first, then ones.
The mouth opens to the greater number.
> greater than · < less than · = equal to
On a number line, the number further to the right is greater.
72 > 27
Look at the circled numbers. Write the missing phrase.
Write <, > or = to compare the numbers.
Same digits, different places: 94 and 49 are not the same number.
Tens, ones and sums
Today I will: change tens and ones, and work out sums, before I compare.
10 ones make 1 ten.
Change them to the same kind. Then compare.
4 tens > 31 ones
Write <, > or = to compare.
Work out the sum first. Then write <, > or =.
Read the words. Write the missing phrase.
Find all the answers
Today I will: find more than one answer, and check if a sentence is true.
24 < □ < 28 — the number is between 24 and 28.
It could be 25, 26 or 27. There are 3 answers!
Write a number in the box. Is there more than one answer?
Complete the sentence.
Read the question. Write a number in the box.
Noor is thinking of a number. It is greater than 76 and less than 80. What could her number be?
76<<80Are there any other answers? How do you know you have found them all?
Is the statement true or false? Change 10 ones into 1 ten first.
Order numbers
Today I will: put numbers in order, from the smallest to the greatest.
Smallest first → ascending order: 14, 40, 41
Greatest first → descending order: 41, 40, 14
Write the numbers in order. Start with the smallest.
