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/g... and in the shorter workbook Math Mammoth Add Subtract 2-A at http://www.mathmammoth.com/add_subtra... - available as an expensive $3.95 instant download.
