Compare fractions (halves, quarters, eighths) that make up a whole by drawing toppings on pizzas and cutting the pizzas into slices!
Visit Gabby's pizza shop to help Adi take pizza orders from customers. Viewers learn fractions that make up a whole by drawing pizza toppings in halves and quarters and cutting the pizzas into one eighth slices.
Learning Objective: To partition objects into equal parts and name the parts, including halves, fourths, and eighths, using words.

While students need to be able to write sentences describing ratio relationships, they also need to see and use the appropriate symbolic notation for ratios. If this is used as a teaching problem, the teacher could ask for the sentences as shown, and then segue into teaching the notation. It is a good idea to ask students to write it both ways (as shown in the solution) at some point as well.
Colorful mosaics, playful flowing forms, imaginative facades—Barcelona shines with the buildings of …
Colorful mosaics, playful flowing forms, imaginative facades—Barcelona shines with the buildings of Antoni Gaudí. How did the son of a Catalan blacksmith become a world-famous architect? The first years of Gaudí's life were challenging. Because of an illness, young Gaudí couldn’t attend school and was often alone. Many of his days were spent out in nature, which he would later call his great teacher. Even during his training as an architect in Barcelona, his teachers were puzzled, wondering: is he a “genius or a fool?” Many considered his unusual ideas eccentric, sometimes even crazy. But Gaudí was simply ahead of his time. His buildings are now a UNESCO (United Nations Educational, Scientific and Cultural Organization) World Heritage Site.

This lesson centers around the How AI Works: Creativity and Imagination? video from the How AI Works video series. Watch this video first before exploring the lesson plan.
Diffusion models generate images. Diffusion AI converts an image to noise, and trains an AI to reverse the process. In this lesson, students learn how AI can generate images, then explore a diffusion AI widget. Finally, the class wraps up with a discussion about whether or not these models are creative.
This lesson can be taught on its own, or as part of a 7-lesson sequence on How AI Works. Duration: 45 minutes
