Problem Solving
Check Your Answer
Make precise calculations and check validity of the results from the context of the problem
Your child will understand the operations necessary to solve computational and conceptual math problems. Additionally, your child will know how to check the validity of his/her work and solutions.

Learning Tips

(1)

As your child is learning addition and subtraction facts to 20, take time each day to quiz him/her on these facts. While doing so, make sure to have some type of math manipulative available to so that may check the validity of your child’s answer to make sure it is correct.

(2)

Computational math (number sentences and problems) is easier for children to internalize and understand. In building your child’s math skills, it is important to spend time building conceptual skills, such as word problems. Rather than practicing addition and subtraction problems using digits only, take time to write out word problems, so that your child will gain proficiency calculating math problems on a conceptual level

(3)

Make math fun! Rather than working strictly with numbers and drill practice, use teachable moments each day to reinforce the math skills and concepts your child is learning. Objects around the house and produce make excellent tools for learning math.

(4)

If your child seems to be progressing well and could benefit from challenge, you should extend his or her learning with math computation to include one and two digit addition and subtraction that might include borrowing and carrying over. This will be an advanced concept for your child, but if he/she is demonstrating proficiency, this will be a welcomed challenge. Before actually doing the calculations, see if your child can guess the correct answer, and then model the math steps to check the validity of the calculations.

(5)

Make math flash cards that not only have digits and number sentences, but also have drawings depicting the number sentence. These drawings will reinforce the validity of the calculations your child is memorizing and give greater meaning to the concepts.
