Lesson 9 - Level 1-2- 3D Visualization- Homework

Pdf Summary

This document is a homework assignment focusing on 3D visualization for a Math Kangaroo class for Levels 1-2. The lessons encourage spatial reasoning and problem-solving skills through various tasks involving cubes and dice.<br /><br />1. The first problem involves Mary creating a shape with some white cubes and 8 gray cubes. Students are asked to determine how many white cubes are not visible from a given image. The solution to this problem indicates that 6 white cubes could not be seen.<br /><br />2. In the second task, students are presented with five different shapes made by gluing cubes together. The objective is to identify which shape uses the fewest cubes. The answer points to shape A as using the least number of cubes.<br /><br />3. The third problem requires understanding the arrangement of numbers on a standard die where opposite faces sum up to the same total. The expected outcomes are pairs of opposite faces: 1 and 6, 3 and 4, and 2 and 5.<br /><br />4. The fourth question concerns Peter building a podium with cubes. Students need to calculate the total number of cubes used based on the visual provided in the homework. The answer is 24 cubes.<br /><br />5. Finally, Martha's activity involves building six towers using a combination of gray and white cubes, ensuring that cubes of the same color do not touch. Each tower consists of 5 cubes. The problem asks for the total count of white cubes across all towers, with the solution indicating 12 white cubes were used.<br /><br />This homework helps engage students in visualizing and solving problems related to three-dimensional objects using cubes, enhancing both their mathematical and spatial intelligence.
