Now that students can build addition tables, they should look for the patterns in them. We introduce them to a variety of things they might want to look for. We also suggest that some students may want to try to make a subtraction table. We have another Lab for making subtraction tables but this can provide some students with an interesting challenge. They should build these two tables side by side to compare their patterns.

Adding to 10 is but on example of a large number of spreadsheets that could be developed to practice addition. We give students two number lines (number bars) to 10, and have them copy a number from each to build a pattern of all the sums to 10. We suggest you encourage students to extend these number bars and practice sums to 20 and beyond. This spreadsheet gives students practice in copy and paste on spreadsheets.
