Gridlock puzzles give students a problem-solving context for their learning, promoting engagement and offering students a sense of satisfaction in completing the grid. To solve the puzzle, students need to engage with the factual information the gridlock is based on, recalling the relationships between ideas and data established in the first part of the activity. For example, they need to recall that three electron pairs corresponds to trigonal planar geometry, or that sulfuric acid forms sulfate salts.Īs they work on the puzzles, students will find themselves referring to the initial data repeatedly, gradually consolidating their knowledge of the relevant facts. What will my students learn? Topic knowledgeĮach puzzle focuses on a topic appropriate to 11–14, 14–16 or 16–18 year old students. For example, set a target time and invite students to try to beat the clock, or encourage groups of students to see who can solve the most. You can also add an extra element of competition or challenge. During lessons, the puzzles can be used flexibly as part of an individual, group or class-based activity. The worksheets are simple to set and can readily be peer or self assessed. Ideally, students should have met at least some of the data the gridlock puzzles are based on already. They are designed as follow up activities to consolidate students’ knowledge, rather than as introductions to a topic. You can use gridlock puzzles during lessons or set them as homework.
