The first thing we need to do is to break down the standard at the different grade levels. It is really helpful to know what your students are expected to do in the grade level before yours and the grade level after yours. This allows you to differentiate your lessons and meet the needs of all your students.

Suggested Books
Identifying main ideas and supporting details can be a challenging skill for your students. Try to gather a collection of informational texts on a wide range of topics that interest your students. I find that nonfiction books about animals, outer space, and famous places work well.

Tips for Teaching Main Ideas and Supporting Details
- Do a main idea and detail sort. Write the sentences from two different paragraphs on sentence strips. There should be one main idea sentence for each paragraph and at least three detail sentences for each paragraph. Have the students sort the sentences to find the main ideas and the supporting details that match each one. This will help them identify the most important piece of information and the key details before they have to find them in a text.
- Use a box diagram to show the main idea and details. When the students are reading independently, have them set up a paper by drawing a big box at the top of the page and three smaller boxes below it. As they read their informational text, they should write the main idea in the big box and a supporting detail in each of the smaller boxes.
- Write a hand summary. After the students create a box diagram, they can use the information to write a hand summary. They should write their sentences as they touch each finger. The thumb is the main idea. The next three fingers are each a supporting detail, and the pinky is a closing sentence.
