An Array of Compound Words




Today we reviewed compound words. 

First, we watched the BrainPop Jr. video.





Something new to students was the idea of different types of compound words. For this, we stopped by the teacher resources from Spelling City




There are THREE different types of compound words, closed, hyphenated, and open compound words! 




Next, Mrs. Yollis got out some compound word cards. Each student was given half of a compound word. The object was to find a student with the other half. Together two students made ONE compound word. 


Once all the compound words were formed, we started making an array to figure out how many compound words we had in all. An array is a multiplication word we recently learned. When you line up objects in equal rows and columns, it makes it easy to get the total, or product

The first attempt is shown below. Students thought they had eight rows of four. So, 8 x 4 = 32 compound words.

Students soon realized that we had eight rows. However, some rows had four compound words and some rows had three compound words.  

We did some figuring, and realized we had 30 words.





Once we realized we had 30 words, we started building real arrays. 



6 rows of 5




15 rows of  2






2 rows of 15







3 rows of 10





What arrays did we miss? 

Leave a comment using at least FOUR compound words!

Multiplication! Multiplication! Multiplication!



We are learning and loving multiplication! 
Multiplication is repeated addition. 



4 + 4 + 4 = 12

3 groups of 4 balloons = 12 balloons
3 and 4 are factors
12 is the product




We've done a plethora of activities to clarify the properties of multiplication and memorize the facts! We have been attacking multiplication in a multitude of ways!

Making Arrays and Applying the Distributive Property of Multiplication 

The Distributive Property states that multiplying a sum by a number is the same as multiplying each addend by the number and then adding the products





6 x 7








We've even been writing about the Distributive Property of Multiplication over on our 365 Blog. 


Aaron's 324 x 5 example:





Keya's 7 x 8 example:



Students have photographed arrays to share on our class 365 blog


In the comment section, leave an equation for one of the following photos! Challenge, can you then apply commutative property or distributive property to your equation? Try to take your comment to a higher level! Here we go!

1. Mrs. Yollis' pan array 









 2.  Kostaki's picture array




3. Kostaki's bead array



4. Keya's pumpkin seed array




5. Ari's shoe array





6. Kate's pencil array 




7. Abigail's chalk array  




8. Keya's tile array
  



9. Lily's crayon array



Advanced: This array uses 3 factors and a set of parenthesis. Good luck!


10. Mrs. Yollis' cup cakes




Again, in the comment section, leave an equation for one of these photos! Challenge, can you then apply commutative property or distributive property to your equation? Try to take your comment to a higher level!
