Instructions
Introduce through sharing: 'Let's see if 4 cubes can be shared into pairs. One for this side, one for that side... 1 pair, 2 pairs. All paired up! 4 is EVEN — everyone gets a partner, no one left out.'
Try an odd number: '5 cubes into pairs: 1 pair, 2 pairs... and one LEFT OVER. 5 is ODD — one cube has no partner!' The concrete pairing makes the even/odd distinction physical and memorable.
Investigate all numbers to 10 — which are even? which are odd? Record findings on a number line with two colours: even numbers one colour, odd numbers another. 'What do you notice about the pattern?'
Rhyme to remember: 'Even numbers end in 0, 2, 4, 6, 8 — they're so great! Odd numbers end in 1, 3, 5, 7, 9 — they're just fine!' For quick identification of larger numbers.
Play even/odd sorting games: call a number, children hold up an even or odd paddle. Build speed gradually — 'is 7 odd or even? Yes, odd! Is 8 odd or even? Even!' Quick-fire rounds build fluency.
Connect to real life: 'If there are 6 of us and we need to get into pairs, will anyone be left out? 6 is even — no one left out! If there were 7 of us? 7 is odd — someone would be the third in a group!'
