Inference activities part 2: Pictures and alt text image descriptions

Information about and fun activities to teach educators and students about alt text descriptions.

The first Inference post in this series provided fun, hands-on activities including Crime Scenes, Garbage Mysteries and Shoe Pairs. (View Inference Activities Part 1 here.) This post, Part 2 in the Inference Series, takes a look at how authors use pictures to provide clues. Picture books and educational materials frequently convey critical information through illustrations; classroom teachers teach ‘inference’ lessons to guide students to use these illustrations to glean information that is not spelled out. Learn how to use picture inference activities with students who are visually impaired and blind?

Image descriptions/alt text: What is it?

Image description – also known as alt text (alternative text) description – is a word, phrase or sentence(s) that can be inserted to describe the nature or content of an image. Image descriptions are announced by screen readers enabling users who are visually impaired to access to information provided through an image. For general purposes, image description and alt text can be used interchangeably. Officially, alt text is used to provide the basic essentials about an image while an image description provides additional details. Learn more about image descriptions and alt text descriptions here.

Incorporating descriptions into classroom activities

Students with visual impairments use image descriptions to better understand what is shown visually through images – things which might not be explained through text. Classroom teachers should be made aware of the need to describe images during all classroom activities and teachers should include alt text descriptions for all digital materials. Teachers of the Visually Impaired (TVIs) can use standard inference lessons to teach students with visual impairments this critical skill – to focus on image descriptions and to use these image descriptions for inference purposes. In the digital classroom, illustrated books and materials have embedded image descriptions, which screen readers will announce. TVIs, are you specifically teaching your students about image descriptions?

NOTE: Alt text can be added to any word-document, PowerPoint Presentation, or digital document. Publishers should, but do not always provide alt text descriptions. Teachers who create their own materials should include alt text descriptions.


Teachers of the Visually Impaired: It is your job to not only make classroom teachers aware of alt text descriptions but also to help them learn HOW to add alt text descriptions to the materials that they use in their classroom for both materials they curate from online sources and materials that they create themselves. This is also a wonderful time to introduce students to guide their peers in how to describe images to them.

Classroom Teachers: Incorporate image descriptions into your inference activities. Having students with vision accurately describe an image will help the whole class learn to pull out important information from an image and will help all students articulate this information. It will also help students with vision learn how to describe items in the environment in a way that is beneficial for their classmate with a visual impairment.

Inferences from images

What is an inference? Students infer when they gather evidence from an image and add what they already know to figure out what is happening in the picture.

The image description should be worded in such a way that the description will provide clues but does not provide the inference. Students need to draw their own conclusions!

Example: The picture below has the image description: “A cartoon lion sitting by wrapped boxes, holding two balloons and wearing a pointed party hat.”

A cartoon lion sitting by wrapped boxes, holding balloons and wearing a pointed party hat.

The image description intentionally does not state anything about a birthday party or the mood of the lion. Students use their own experience and/or knowledge to infer that this picture is about a happy lion at a birthday party.

The attached Infer or Not to Infer worksheet below, provides three sentences; two can be inferred and one is not inferred.

Infer or Not to Infer activity

Have Fun Teaching has shared free online worksheet called to Infer or Not to Infer. (Download Infer or Not to Infer worksheet from their website.) This worksheet displays a simple picture and then three sentences associated with each picture. The student chooses which sentence(s) can be inferred from the picture and which sentence(s) cannot be inferred.

If done as a group activity, the teacher can model how to describe the image without giving away pertinent details. If the class already knows how to describe the image correctly, the teacher may choose to have a student describe the image. Read the sentences aloud and discuss which sentences can be inferred or not inferred and why.

If the activity is done individually, the teacher can use the modified version of this activity (which includes alt text descriptions).

The original To Infer or Not to Infer worksheet includes an additional print activity for each image: students are asked to write their Inference #1 in the first box and then their Reason in the second box. Students are then asked to repeat this activity for each image. Students can complete this activity digitally in a document or teachers can opt to create an accessible assignment using an app such as Google Forms.

For additional free inference image materials, download Making Inferences Using Pictures 1 and Making Inferences Using Pictures 2 from the www.HaveFunTeaching website. For your convenience, these worksheets have been made accessible by adding image descriptions for students who use screen readers.
