New words
count · say the numbers in order, one for each thinghow many · the number of things in a setset · a group of things that go together
Explanation

Numbers are everywhere: on buses, on doors, on football shirts and on food packets. Sometimes a number is just a name, like bus number 7. Other times a number tells us how many things there are. To find out how many, we count. Point to each object and say one number for it: 1, 2, 3, 4. Do not skip an object and do not count one twice. The last number you say is how many there are in the set.

Worked examples
Count the apples: touch each one and say 1, 2, 3, 4. The last number is 4, so there are 4 apples.
Count the pencils: 1, 2, 3, 4, 5, 6. There are 6 pencils. If we move them around, there are still 6.
Class activity

Number hunt: walk around the classroom or home and find 5 places where you can see a number (a clock, a door, a book, a phone). Say each number out loud. Then count the chairs at your table.
