During your child's second grade year, he will learn to identify time in five-minute increments and solve problems asking for elapsed time. A sample problem might ask, "If James leaves his house at 7:10 am and arrives at school at 7:25 am, how much times does it take him to get to school?" He may also be asked to determine if noon should be written at 12:00 am or 12:00 pm.
Your second grade student needs to understand the value of money and solve simple money word problems. She might compute the value of two dimes, four pennies, three quarters and a nickel and write the value using the dollar sign and the decimal point. She can solve problems such as $3.05+$4.29 or $5.25--$2.67.
By year's end, your second grade student can skip-count forward and backward by twos, threes, fives and tens. He can diagram numbers using a number line. He can write a number in expanded notation such as 375 = 300+70+5. He can round numbers to the nearest 10 and use the signs for greater than, less than and equal to. He will be able to tell you whether a number is odd or even.
By the completion of the second grade, your child will understand fractions such as one-half, one-third, one-fourth, one-fifth, one-sixth, one-eighth and one-tenth. She will learn how to match equivalent fractions that equal one. If you give her six objects and ask her to circle one-half or one-third of the objects, she can complete the problem. She will also be able to understand that one-half and one-half equals one.
Before the end of the second grade, your student will use a ruler to measure lines in standard and metric measurements. He will use a ruler to draw two-inch or two-centimeter lines. He will know how to use and compare standard and metric liquid measures such as four cups and one liter. He will also know how to weigh objects in pounds.
During the second grade, your student will learn to multiply numbers by one, two, three, four, five, zero, and 10. She will estimate sums and differences and be able to check her estimate. She will solve up to three-digit addition and subtraction problems such as 245-100 and 345+48. Your child will write addition and subtraction problems horizontally and vertically. She will solve addition problems with up to three addends such as 256+345+167 and be able to solve them in any order. She will practice doubling numbers by adding a number to itself such as 321+321.
