I introduced the concept of odd and even today to my six year old and thought I would share my impromptu lesson.
1. Draw one dot with the numeral one over it:
2. Tell student that the one dot is alone, he has no partner (or friend). Because he is alone, we call him odd. Write the word odd under the dot):
Tell student that Allah tells us He is odd, He is just one.
3. Next to the numeral 1, write a 2 with two dots under it:
4. Make a circle around the two dots under the numeral two making one group of two dots.
5. Tell student that the two dots make a pair (a pair is two things), the dots are not alone they are paired up. Since no one is left out (no dots, that is), we call the number two even. Write the word even under the two dots.
(the two dots under the two are circled into one group).
6. Next to the 2, write a 3 with 3 dots under it.
7. Circle two dots to make a pair. Point to the one remaining dot and say, after we have made a pair, we have 1 dot left over. When we have one dot left over, we say the number is odd, so 3 is an odd number. Write odd under the three dots.
8. Repeat this process for numbers 4-10.
After you get to about five, have student circle the pairs of dots (you may find that the student takes the initiative to circle the dots on her own).
Have student tell you if the number is odd or even by looking at whether or not there is an unpaired dot.
Be sure to write the word odd or even under each set of dots. (will come in handy next).
9. When you have finished 10, go back to your drawings and start from the left and tell student to tell you which numbers are odd (they have odd written under them). You (the teacher) write all the numbers as student says them. So you will have, 1, 3, 5, 7, 9. Over these numbers write the word odd.
10. Do the same thing (as in number 9) for the even numbers and write even over these numbers that student calls out: 2, 4, 6, 8.
11. Explain to student that the number 10 has two digits, a one and a zero. Ask student what digit the 10 ends in. (zero). Tell student that a number ending in 0 is even and add this to your even number list above: 0, 2, 4, 6, 8.
12. Tell student when a number (no matter how big (i.e. how many digits) it has, when it ends in 1, 3, 5, 7, 9 (pointing to your list), the number is odd.
Give student a number such as 41. Ask what number it ends in (1) and then if it is odd or even (refer student to your chart you just made if necessary).
Tell student when a number (no matter how big (i.e. how many digits) it has, when it ends in o, 2, 4, 6, 8 (pointing to your list), the number is even.
Give student the number 32. Ask what number it ends in (2) and then if it is odd or even (refer student to your chart you just made if necessary).
13. Give student several numbers (from 1 digit up to 5 or whatever) and have student tell if that number is odd or even, you might want to have student write the words odd or even for each one. If necessary, draw a line under the last digit as a reminder of where to look to tell if the number is odd or even. You can let student use the chart.
For subsequent sessions/practice
Give student worksheets of numbers to write whether the numbers are odd or even. You can have student draw dots corresponding to the last digit and make pairs to determine if the number is odd/even. When student understands, she can use the chart or do the work on her own without it.
Be sure to review the concept daily (orally or written).
Doesn’t have to be anything big, just call out a few numbers and ask student if they are odd/even. You might also incorporate the review into lessons; for example, if student is working on addition, ask if the sum of the problem they just did is odd or even.
