This is how my students learn how to compare and contrast.
I pre-teach some vocabulary (in this case animals), and ask them to choose two animals. Then, they have to group the words according to their similarities or differences.
Once they've learnt how to classify the information, they can start working with more complex sentences.

This product includes 20 task cards with real life problems where the students have to compare and order decimal numbers.

Includes:

- 20 color task cards

- 20 white and black task cards

My suggestion if that you print them, laminate them and paste them around the classroom for students to walk from to the other solving the problems.

Are you looking for a fun way to practice compare decimals?

This resource is for you! This self-checking digital puzzle includes 16 exercises where students have to add or subtract mixed numbers. Every time they answer correctly a piece of a mystery puzzle will appear! If they answer incorrectly, the cell will turn red for students to check their work and try again!

It accepts simplified answers.

You will download a PDF that has a link for a Google Sheet with the activity for the students. It is self-checking and you will also have the answers in the PDF as a reference.

Use it when your students need to practise reading skills. This one is about Pedro and Juan. Your students have to identify similarities and differences between these two characters. Use a Venn Diagram to write the answers.

This test is about giraffes and birds.
The students read and identify the story elements. Then, they have to compare and contrast both animals in a venn diagram.
Finally, you can decide asking them to write sentences about animals.

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.

The following lesson contains 43 slides full of activities, questions, examples and definitions of the main five evidences of evolution: Fossils, Embryology, Compared Anatomy, Biogeography and Molecular Biology. In here you will find examples of fossils, the types of fossils, some activities that work skills like data analysis, interpretations of models, comparison between two or more situations and very interesting facts that will make your students be a little bit more in love with science.

This interactive notebook is designed with the Launch, Explore, Discuss model. I provide a brief explanation at the beginning of the notebook to familiarize you with this model, and I also detail the steps as we use them.

Esta guía de trabajo puede usarse en las clases sincrónicas, asincrónicas o  presenciales. 
Los estudiantes tienen que resolver problemas de comparación de números aplicando dos estrategias distintas, tachando o encerrando en círculo la respuesta. 
Puedes ir proporcionando preguntas a medida que resuelven si la situación lo permite como por ejemplo:
