A complete unit with direct instruction to the student, ample practice problems and word problems. Common Core aligned. Great for independent practice/homework.
This unit deals with addition facts within 0-10 (in a few occasions numbers between 10 and 20 are used) and is suitable for first grade (and somewhat for kindergarten).
The first lesson introduces “missing addend” problems. We first use pictures, and gradually get to the abstract problems with symbols only, such as 1 + __ = 5. Keep in mind that children may confuse this problem with 1 + 5 = __.
You can word these problems like this: “1 and how many more makes 5?” You can MODEL them by drawing: First draw 1 ball. Tell the child that we need to have a total of 5 balls. He is to draw more until there are five balls. In the missing addend problem, the number of balls the child has to draw is the number that goes on the empty line. So, first there is one ball, then we need to add (draw) some more to make 5. But how many more were drawn?
After that, the unit contains many lessons called Sums with... whose goal is to help the child memorize the addition facts.
My approach to memorization is many-fold:
1. Structured drill, such as you see in the lessons 'Sums with 5,' 'Sums with 6,' and so on. This is not random drill, because you will start it by showing the pattern or the structure in the facts. This will help the student to tie the addition facts in with a context and help him understand the facts more on a conceptual level, instead of merely memorizing them at random. In sums with 5, the child learns the number combinations that add up to 5: 0 and 5, 1 and 4, and 2 and 3. This understanding is the basis for the drills.
2. Using addition facts in games, in math problems, everyday life, or anywhere else. Games are especially useful because they help children like mathematics.
3. Random drilling may also be used as a tool among others.
4. Memory helps such as silly mnemonics or writing math facts on a poster and hanging it on the wall.
These are not necessary for all children.
However, keep in mind that children will need LOTS of opportunities to add numbers to actually memorize the facts, so the memorization may not totally occur as your child works through this book. These same addition facts are further studied and used when students learn subtraction.
You can print the whole unit and make it into a workbook to fully teach these topics (replacing your math curriculum). Answer key is included.
I wish you success in your math teaching!
