2.OA.3. 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. 2.OA.4. 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. || ===‍‍‍**Anchor Standard/Mathematical Practice(s)**=== __Mathematical Practices__ MP2. Reason abstractly and quantitatively. MP3. Construct viable arguments and critique the reasoning of others. MP7. Look for and make use of structure. MP8.

Using ice cube trays, children can use a variety of manipulatives to make a variety of arrays. Ice cube trays can also be put together to create different arrays. Based on the commutative property of addition, students can add either the rows or the columns and still arrive at the same solution. (Integrated with Science: Matter, Properties and Change - 2.P.2.1, 2.P.2.2, & 2.P.2.3) Students fill their ice cube tray with water and talk about liquids. //Is this still an array?// Next Day: Ice cube trays are frozen and students discuss liquids changing to solids. //Is this still an array?// Students demonstrate the different addition equations that equal 1 ice cube tray. Challenge: What addition equations equal 2 trays? Does it matter if you join the trays end for end or top and bottom?

Students can use their red & yellow counters to make arrays.
