2nd Grade Math

By the end of second grade, students should be able to demonstrate the following math abilities. Many skills are worked on throughout the year and build on each other.

Adding and subtracting
 

• Quickly and accurately add and subtract within 20 (ex. 17 - 8 or 6 + 7); know from memory all addition facts.
• Solve word problems that involve adding and subtracting two-digit numbers. For example, Mrs. Deering’s class has 26 children, and Mr. Klein’s class has 31 children. How many cupcakes will they need for each child if they are having a party together? Children in second grade often use strategies to do this. For example, 26 + 31 can be added quickly by adding the tens (50) and adding the ones (7). Or, some children may start at 26, add 30 to get 56, then add one more.
• Tell which of two three-digit numbers is larger by comparing hundreds, tens and ones. Write any number up to 1000 when told the number name (ex. “Write seven hundred fifty six.”)
• Begin to add and subtract within 1000, using base ten blocks, drawings or strategies based on place value.

Measuring lengths and working with time and money
 

• Measure objects in inches and feet using rulers, yardsticks, and measuring tapes.
• Tell time on both digital clocks and clocks with hands, to the nearest five minutes, using a.m. and p.m.
• Count money to find the total amount of dollars and coins.

Geometry and shapes
 

• Recognize and draw shapes such as triangles, quadrilaterals, pentagons, hexagons and cubes.
• Divide circles and rectangles into two, three or four equal parts. Name the parts using the words halves, thirds and fourths.
