This is a set of 24 QR code task cards aligned to the second grade common core standards:
Determine whether a group of objects (up to 20) has an odd or even number of members, e.g., by pairing objects or counting them by 2s; write an equation to express an even number as a sum of two equal addends.
Use addition to find the total number of objects arranged in rectangular arrays with up to 5 rows and up to 5 columns; write an equation to express the total as a sum of equal addends.
Students will need to:
- determine which doubles fact could help them solve a near-doubles equation
- write a doubles equation to match a picture
- double a number
- determine which doubles fact equals an even number
The sums of the doubles equations in this set go up to 20, so the highest number that students will be asked to double is 10.
