I love craft activities. This is focused on opposites/antonyms but you can try with different topics. The students should follow the instructions (they are short and clear) . They can also work in pairs. Give one cloud to each student and encourage him/her to find a match. Then, they can color the rainbow together and use it to decorate the classroom. 

Hola, les comparto estas flashcards sobre opuestos en inglés son 14 tarjetas de apoyo para aprender los opposites en inglés, se pueden imprimir o bien usar como recurso digital para clases virtuales o presenciales 

This is good to introduce antonyms. Students will check different examples. It is mainly focused on the vocabulary my students know, but you can adapt it to your own needs.
Send me a message and I'll send you the PPT.

The ants need to find their match! The students should find the antonym and draw lines to match the ants. I used the same vocabulary from the Antonyms PPT.
Do you like the border? It is from https://pageborders.org/ 

The students already know some antonyms. The next step could be asking them to rewrite sentences using opposites. I wrote the opposites, but you can erase them and make it more challenging for your students. You can also remind them to use capital letter at the beginning and a period at the end of a sentence.

I love this story from Erik Brooks. I downloaded it from youtube.
https://www.youtube.com/watch?v=1GLwXMBeMHg "Polar Opposites"
It's great for practising listening comprehension but also to talk about similarities and differences. The story is about a polar bear and a penguin who live on opposite sides of the world. They are different but they also have some things in common...They live in cold places, they are vertebrates... Try to elicit some more answers from your students!
After your students have listened and discussed about the story, they can write some similarities and differences between Alex and Zina. I'd project it on the board and check the answers together. Since there are not so many similarities in the story, your students will have to use their previous knowledge about the animals.
