Kindergarten: Counting

Warm up with a quick recall on the board. Count real objects out loud, touching each one once, then match the count to the written numeral. Practise counting on from a number, not always from one.

Counting is matching each object to one number word, in order, to find how many. It sounds simple but rests on several ideas at once: saying the number names in the right order, touching each object exactly once, and knowing the last number said is the total (the cardinal principle). Model the method clearly, thinking aloud:

• Practise the count sequence out loud first (one, two, three) until it is smooth, since this is separate from counting objects.
• Teach one-to-one matching: touch or move each object as its number is said, so none is counted twice or skipped.
• Stress the last-number rule: the final number said is how many there are altogether, not just the name of the last object.
• Fill in missing numbers on a number track or hundred square to build the sequence forwards and backwards.
• Count real collections of different sizes and arrangements so students learn the total does not change when objects are rearranged.

Do the first few questions of the practice worksheet together, one child explaining each step. Check for understanding before releasing the class to work alone.

Students complete the worksheet independently. Hand out the three difficulty levels below so every child works at the right stretch.

Circulate and look for these, they are the usual sticking points:

• Reciting the number names but not matching one number to one object.
• Counting an object twice or skipping one in a scattered group.
• Not knowing the last number counted is the total, so recounting when asked how many.
• Thinking a spread-out row has more than the same objects pushed together.
• Skipping or double-counting objects (weak one-to-one correspondence), and thinking the last number said is just a label rather than the total.

Pull the class back together. Ask one child to explain counting in their own words, pose a single check question everyone answers on a mini whiteboard, and name what you will build on next lesson.

Use the independent worksheet as the evidence. A child who can complete it accurately and explain one answer has met the objective; anyone who cannot needs the easier level and a short reteach next session.
