Objective: To gauge students' prior knowledge before starting a unit.

Example Activity: Use a "KWL Chart" (Know, Want to Know, Learned).

• Instructions: Ask students to fill out the first two columns ("Know" and "Want to Know") before starting the unit. For instance, in a PYP science unit on ecosystems, students write what they already know about ecosystems and what they want to learn. For MYP or DP, this can adapt to topics in biology, geography, or environmental systems.

Objective: To evaluate cumulative understanding at the end of a unit.

Example Activity: Project Presentation.

• Instructions: Assign students to create a presentation on the topic (e.g., in a PYP unit on ecosystems, they present on a specific ecosystem). MYP students might create a report analyzing the biodiversity of a specific area, while DP students could write an essay discussing human impact on a particular ecosystem, citing scientific studies.

Objective: To check understanding during the learning process and adjust teaching as needed.

Example Activity: "Exit Ticket."

• Instructions: At the end of a class, ask students to answer one or two short questions based on the day's content (e.g., "Describe one thing you learned about ecosystems today"). In MYP, it could focus on explaining one concept about food chains, while in DP, it might involve applying a concept to a real-world scenario.
