Students will be adding (sums) and subtracting (differences) using many different mental strategies. They will be finding friendly numbers to make a 10, along with decomposing (breaking apart) numbers to make adding and subtracting easier.
Students will learn the importance of VALUE in a number and what each digit represents. They will be exploring different ways to represent a number using standard form (245), expanded form (200 + 40 + 5), unit/Base-10 numeral form (2 one hundreds, 4 tens, 5 ones), word form (two hundred forty-five), and picture form (use of Base-10 blocks to build and represent each value).
Students can use MANY DIFFERENT strategies to help them add or subtract. There is not one strategy that they must use, but I will expose students to ALL of them.
*NEW GA Standard - They will then get to CHOOSE their BEST and MOST EFFICIENT strategy!
Students will need to be able to identify coins and their values. They will also be representing a given amount in multiple ways and need to be able to make change from $1.
*NEW GA Standard - Students will be required to skip count by 25's starting at 0. We will relate this to money (quarters).
*NEW GA Standard - Students are only required to master measuring with inches, feet, and yards, BUT metric units (centimeters and meters) will still be present on MAP.
Students will be describing 2-D and 3-D shapes based on their attributes (sides, angles, faces, edges, and vertices).
Students will use shapes to transition into making fractions by showing halves, thirds, and fourths.
Students will be telling time by the quarter hours and to the nearest 5-minute.
*NEW GA Standard - Students will be expected to solve elapsed time problems to express how much time has passed.
Students will be making equal groups of a given amount to create arrays. These arrays will be formed by rows and columns. Students will then match the array to a repeated addition sentence to show how many are in each row how ever many times. This will lead into creating multiplication equations (and then division sentences - fact families).
This standard addresses how numbers can shrink (count backward) or grow (count forward). 2nd grade students should be able to skip count forward and backward by 5's, 10's, and 100's from any starting number.
