Comparing groups: more or fewer
Compare two groups of objects to determine which has more, fewer, or whether they are equal, using matching and counting strategies
What a learner can do afterwards
- Use one-to-one matching to compare two groups
- State which group has more/fewer after counting both
- Use the language 'equal to', 'more than', 'less than', 'fewer', 'most', 'least'

Look at two groups of things. Which one has more? Which one has fewer? Match one thing from each group. The group with leftovers has more. Or count both groups. The bigger number means more. Most means the biggest amount of all. Least means the smallest amount of all.
Mia has 4 apples. Zoe has 6 apples. Mia matches each apple to one of Zoe's. Two of Zoe's apples have no match. Zoe has more apples.
Match every thing, one to one. No leftovers on either side means the groups are equal.
Match or count both groups. Leftovers show which one has more.

Comparison symbols review
Comparing tells which group is bigger. Line the groups up and match them one to one. The group with leftovers is bigger.
We use special words for comparing: more than, fewer than, and equal to. 5 is more than 3. 3 is fewer than 5. 4 and 4 are equal.
1.4: Topic D- Ordering Numerals
Numbers sit in order: 1, 2, 3, 4, 5, and on. A number that comes later is bigger than one that comes earlier.
To compare 4 and 7, ask which comes later. 7 comes later, so 7 is more.
1.2: Topic B- Counting
Count each group carefully before you compare. Touch every object once and say the numbers in order.
Only compare after both totals are known. Guessing from how big the pile looks can trick you, because small things can pile up high.
1.1 Introduction to Whole Numbers
Most and least pick the winners. Most means the biggest group of all. Least means the smallest group of all.
For 2, 6, and 4, the most is 6 and the least is 2. Line the numbers up in order and the ends show the answers.
