Interactive video lesson plan for: Tricks & Strategies for Addition Facts - Grade 2 Math

Activity overview:

Help children learn and memorize addition facts with these simple "tricks" or strategies (for grades 1 and 2 math).

I start out with the pattern for "Sums with 7" where I simply find all the additions where the sum is 7 (7 + 0, 6 + 1, 5 + 2, and 4 + 3). It helps to write them in order so that children can see the easy pattern in them, and also to use objects or drawings to show the groupings.

This idea is also used with other numbers. For example, children need to study sums of 8, sums of 9, and so on in the same manner.

Next I explain the 9-trick. To add 9 + 6, imagine that 9 wants to be 10, so it asks 6 to give it "one". That way 9 + 6 is changed to the sum 10 + 5 which is easy to solve.

The 8-trick is similar. To solve 8 + 5, imagine that 8 wants to be 10 and it asks 5 to give it "two". Eight loses two, and the problem becomes 10 + 3.

After children learn their doubles, they can then use the trick "doubles plus one more". For example, once you know that 8 + 8 = 16, then 8 + 9 is just one more, or 17.

I also show how to do random drill using the structure of an addition table.

These ideas and strategies are used in Math Mammoth grade 2 curriculum at http://www.mathmammoth.com/complete/grade_2.php and in the shorter workbook Math Mammoth Add & Subtract 2-A at http://www.mathmammoth.com/add_subtract_2A.php - available as an expensive $3.95 instant download.
