### Add using single-digit addition facts Worksheets

How to use single-digit sums to support solutions for analogous sums?

Ensure the students have a solid grasp of single-digit addition. Practice these frequently using manipulatives (counters, blocks, etc.) or number lines.
2. Build on Known Facts:
Present problems like 8 + 4, 18 + 4, and 28 + 4.
Guide the students to notice the common element: 8 + 4 in each problem.
Remind them of the answer to 8 + 4 (which should be well-known) and build upon it.
3. Break Down Larger Sums:
Encourage the students to visualize larger sums as combinations of smaller, familiar sums.
For example, 27 + 5 can be seen as 20 + 7 + 5.
Break it down further: 7 + 5 = 12, then add the 20 to get 32.
4. Encourage Mental Strategies:
As the students become more comfortable, encourage them to use mental strategies like:
Counting on from the larger number (e.g., 27 + 5, count on 5 from 27).
Using “make a ten” strategies (e.g., 27 + 5, take 3 from 5 to make 27 + 3 = 30, then add the remaining 2).
