Description
Counting on is the first addition strategy that lets a child stop counting everything from one. Instead of counting eight dots and then three more, the child holds the 8 in their head and counts 9, 10, 11. The adding three counting on worksheet practises that one move with a friendly number: three. Every problem adds 3, every sum lands between 8 and 14, and a start box plus three dots shows exactly where the counting begins and ends.
About This Worksheet
The adding three counting on worksheet is two pages: the practice on page one and a complete answer key on page two. Part A has six cards. Each card shows the starting number in a box and three dots beside it, so the child says the number in the box and then touches each dot while counting on. The number sentence and a writing line sit right under the picture. Part B takes the pictures away and gives four more number sentences, and in two of them the 3 comes first, so the child has to find the bigger number before counting on. The answer key numbers every dot, which makes it easy to see exactly where a child’s counting went wrong. Use it for a small-group lesson, a math centre, morning work, or homework.
What’s Included
- Six count-on cards with a start number box and three dots to count
- Four number sentences without pictures, with the 3 placed first in two of them
- Every sum from 8 to 14, within 20 for 1st grade
- Circled problem numbers and a roomy writing line for each answer
- A full answer key page that numbers each counted dot
Three Reasons This Helps Kids
- It builds a faster strategy. Counting on from the bigger number is quicker and more accurate than counting all, and it prepares children for mental math.
- The picture fades away. Part A gives support with dots, and Part B asks the child to do the same thinking with numbers only.
- It teaches the child to choose. Putting the 3 first in some problems shows that 3 + 9 and 9 + 3 have the same total, so it is smart to start with the 9.
Ideas for Teachers and Parents
Before the page, put a number card on the table and three counters beside it. Have the child tap the card and say its number, then tap each counter and count on out loud. Try the same thing with the counters first and the card second, and talk about which way is easier. After the sheet, ask children to make up their own count-on problem for a partner. At home this 1st grade addition worksheet takes about ten minutes, and the Have Fun Teaching Adding 3 Song gives the same facts a catchy review.
