As your child heads into the second grade it is important to make sure you know exactly what they will be expected to learn so that you can prepare them as the summer wanes and understand where they are in regards to the rest of their class. While first grade covered some basic math skills, second grade is where they will really get into problem solving and equation solving in a very real way.
In second grade, children are no longer expected to just be able to spout different equations but they are now going to be expected to tell why a certain number plus a certain number equals what it does. Story problems are something that will be inserted into the curriculum more and more and will therefore encourage the student to think around the problem instead of taking it head on. It is very much encouraged that you begin to work with your child at home on these types of story problems and even find better ways to get you kid to see the problem in his or her head. Even if you do not know the story problems that will definitely be used during this year it is good to help your child develop a system to solve like problems.
Measurements are another area where the students will focus much of their attention. Inches, feet, yards and smaller denominations like centimeters and millimeters will all be terms they will be introduced to as well as shown just why it is important to get these measurements as precise as possible. Finally the value of money becomes a greater part of the curriculum when talking about math in second grade. Students will be introduced to all the different variations of coins and they will begin to see how you can make different amounts with selected dollars and cents.
