Try using this PPT when teaching compund words. First, I start with a brief explanation of what a compound word is. Then, I elicit some examples. Finally, the students see the pictures and try to guess the compound word. You can also try giving them a set of cards and ask them to match them and make as many compound words as they can.
Send me a message and I'll send you the PPT

I downloaded these cards from https://www.twinkl.cl/
I love them! You can set a learning center and your students can start playing on their own. They just have to look at the pictures and start making matches. You can always add more pictures.
 

This idea is from https://ofamilylearningtogether.com/
It is important to have a diverse set of activities in order to maximaze the learning opportunities. I like the link you can make between pictures and words. Just don't forget to use English as much as you can! Instructions, questions, etc. It may be good to ask them to spell the words. 

This is another type of craft you can use when teaching compound words. 
The students have to cut out the eggs and match them with the compound word (chicks). 
If you want to make it more challenging, try giving them half egg and ask them to find a match.

Try playing this game from education.com

I'm pretty sure your students would like it! They have to feed a cat by matching compound words. The words are shaped like half of a fish. 

I prepared this worksheet to practise compound words. The students have to look at the pictures and write the new word. 
I like adding borders to my worksheets. I think they should be colorful and attractive. 

Poster to teach compound nouns. This poster shows how to nouns can be joined to form a compound noun. This poster shows how nouns can be put together to make a compound noun. It is super colorful for students who are more visual, and it can also be shown in virtual classes.
