This learning resource is titled 'Number City Navigator: The Map to 100'. The goal of the lesson is to teach students how to navigate a hundreds chart by using interactive activities where they move between rows and columns to identify specific addresses. The activities include 'Walking Down a Block', which introduces vertical movements along the chart, demonstrating how moving down changes the tens digit while keeping the ones digit the same. Students will compare vertical moves (like from 42 to 52) with horizontal moves (like from 42 to 43) to see how numerical values change. The resource also offers guided practice where students will circle starting addresses and draw arrows to target addresses with the aid of colored markers. Lastly, the 'Challenge Task - Double Step Delivery!' allows students to think critically as they determine a final delivery address based on specified movements across the hundreds chart. Overall, this resource emphasizes understanding number relationships and spatial reasoning on a hundreds chart.
