In Grade 2, instructional time should focus on four critical areas:
(1) extending understanding of baseten notation;
(2) building fluency with addition and subtraction;
(3) using standard units of measure; and
(4) describing and analyzing shapes.
Southern Cross Consultancy have developed over 100 handson games, Math centers and activities for use in the classroom utilizing the "I Can" format to reinforce the studentfriendly instructions, reinforcing student independence.
The Grade 2 Math CCSS Games Packet includes:

2NBT1. Understand that the three digits of a threedigit number represent amounts of hundreds, tens, and ones; e.g., 706 equals 7 hundreds, 0 tens, and 6 ones. 2NBT1a. 100 can be thought of as a bundle of ten tens — called a “hundred.” 2NBT1b. The numbers 100, 200, 300, 400, 500, 600, 700, 800, 900 refer to one, two, three, four, five, six, seven, eight, or nine hundreds (and 0 tens and 0 ones).

2NBT7. Add and subtract within 1000, using concrete models or drawings and strategies based on place value, properties of operations, and/or the relationship between addition and subtraction; relate the strategy to a written method. Understand that in adding or subtracting threedigit numbers, one adds or subtracts hundreds and hundreds, tens and tens, ones and ones; and sometimes it is necessary to compose or decompose tens or hundreds.

MEASUREMENT AND DATA  
Measure and estimate lengths in standard units  
2MD1. Measure the length of an object by selecting and using appropriate tools such as rulers, yardsticks, meter sticks, and measuring tapes. 


2MD2. Measure the length of an object twice, using length units of different lengths for the two measurements; describe how the two measurements relate to the size of the unit chosen.  Measuring in Inches and Centimeters  
2MD3. Estimate lengths using units of inches, feet, centimeters, and meters.  Estimating and Measuring – Centimeters* Estimating and Measuring – Feet* Estimating and Measuring – Inches* Estimating and Measuring – Meters* Finding Foot Measurements Finding Meter Measurements
