Compare amounts through ten using counting order and one-to-one matching.

Today we compare two amounts, check equality and find extra or missing objects by pairing.
| Term | What it means |
|---|---|
| Equal | The same amount. |
| Greater | A larger amount. |
Give each toy one counter. If counters remain after every toy has one, there are more counters than toys. If some toys wait without a counter, there are fewer counters. If everything pairs with nothing left, the amounts are equal. Start with one object from each group; do not give two counters to the same toy.

Four pairs leave two extra counters.
Greater means a larger amount; less means a smaller amount. Counting order can help: seven comes after five, so seven objects are more than five objects. This compares quantity, not the size of one object. Spreading a smaller group over a longer row cannot make its count greater. Pair or count to check appearances.
Set out brushes for toy workers, one each. Describe any extras or missing brushes. Change the number of workers and check whether your supplies are still enough.
[Six] [Eight]
Compare filled spaces.
Six pairs and two extras.
The second frame has extra dots.
Name the greater amount.
Eight is greater than six.
Six objects cannot use all eight partners.
[Five] [Five]
Pair corresponding dots.
Five pairs.
Every dot gets one partner.
Check for leftovers.
