Counting one more or one less up to 10 with dots
Learn one less and one more
One less is the number just before a number. One more is the number just after it. With dots, take away one dot to show one less, or add one dot to show one more.
Each dot represents one. Count each dot once. The last number you say tells how many dots there are.
Start with 3 dots. Take away 1 dot to make 2. Add 1 dot to make 4.
Three is between two and four. Two is one less than three, and four is one more.
Count backward to find one less. Count forward to find one more.
One less and one more than 1
One less than 1 is 0. One more than 1 is 2.
Zero means none. You can show zero with an empty group.
Start with one dot. Take it away to make zero, or add one dot to make two.
One less than 1 is 0. One more than 1 is 2.
Zero means there are no objects in the group.
One less and one more than 2
One less than 2 is 1. One more than 2 is 3.
Start with two dots. Take away one dot to make one, or add one dot to make three.
One less is 1. The number is 2. One more is 3.
Each dot counts as one, no matter what color it is.
One less and one more than 3
One less than 3 is 2. One more than 3 is 4.
Count three dots. Take away one to make two, or add one to make four.
One less is 2. The number is 3. One more is 4.
Touch or point to each dot as you count it.
One less and one more than 4
One less than 4 is 3. One more than 4 is 5.
Four dots become three when one is taken away. Adding one makes five.
One less is 3. The number is 4. One more is 5.
Say the numbers in order: 3, 4, 5.
One less and one more than 5
One less than 5 is 4. One more than 5 is 6.
Start with five dots. Take away one to get four. Add one to get six.
One less is 4. The number is 5. One more is 6.
Five is one more than four and one less than six.
One less and one more than 6
One less than 6 is 5. One more than 6 is 7.
Six dots become five when one is removed. Add one dot to make seven.
One less is 5. The number is 6. One more is 7.
When you add one, the number increases by one.
One less and one more than 7
One less than 7 is 6. One more than 7 is 8.
Seven dots become six when one is taken away. Adding one makes eight.
One less is 6. The number is 7. One more is 8.
Count slowly and point to each dot once.
One less and one more than 8
One less than 8 is 7. One more than 8 is 9.
Take one dot away from eight to make seven. Add one dot to make nine.
One less is 7. The number is 8. One more is 9.
Eight is between seven and nine.
One less and one more than 9
One less than 9 is 8. One more than 9 is 10.
Nine dots become eight when one is taken away. Add one dot to make ten.
One less is 8. The number is 9. One more is 10.
Ten is one more than nine.
One less than 10; extending to 11
One less than 10 is 9. One more than 10 is 11. Finding one more than 10 extends beyond the main practice range, which uses starting numbers from 1 to 10.
Take one dot away from ten to make nine. Add one dot to make eleven.
One less is 9. The number is 10. One more is 11.
After ten comes eleven. Keep counting in order: 9, 10, 11.
