1. Math Primary 3 Numbers up to 1000 By Ms. Maya

2. What will we learn today? Numbers up to 1000 Place values Numbers and words Whole Numbers Numbers up to 10000

3. Ones unit Count the ones! There are 8 ones. The value of 8 ones is 8. Count the ones! There are 10 ones. 10 ones make 1 ten.

4. Tens sticks Count the tens! There are 2 tens. The value of 2 tens is 20. Count the tens! There are 10 tens. 10 tens make 1 hundred.

5. Hundreds flats Count the hundreds! There are 2 hundreds. The value of 2 hundreds is 200 Count the hundreds! There are 10 hundreds. 10 hundreds make 1 thousand.

6. Let’s try 11 ones 1 ten1 one 11

7. Let’s try 11 tens 1 hundred + 1 ten 100+ 10 = 110

8. 4 hundreds + 3 tens + 2 ones The number is 432 The value of digit 4 is 400 The value of digit 3 is 30 The value of digit 2 is 2

9. 100one hundred 200 two hundred …….. 1000 one thousand.  125 = one hundred and twenty–five  346 = three hundred and forty-six Numbers and Words We put and to separate hundred and tens-ones. Do not forget to put hyphen (-) to separate tens and ones.

10. Always remember! We read and write 300 as “three hundred” NOT “three hundreds” 500 = five hundred 500 = five hundreds

11. Counting on and Counting back Counting on and Counting back in tens

12. Counting on and Counting back Counting on and Counting back in hundreds 210310410510610710810910 100 more/100 less than a given number. When finding 100 more/less than a given number, they will see that only the numbers in hundreds place change. 234334434
