Pdf Summary

The document provides solution suggestions for the Math Kangaroo competition held on March 21, 2019, specifically for Levels 1 and 2. The solutions cover a variety of mathematical problems designed for young students, focusing on fundamental arithmetic, logic, and problem-solving skills. Here's a summary of some key solutions:<br /><br />1. **Understanding Numbers and Comparisons**: For a question regarding numbers less than 7, the answer (D) highlights that none of the numbers is less than 7.<br /><br />2. **Patterns and Arrangements**: In a problem related to arranging beads, solution (C) notes that specific conditions about bead placement are lacking in existing necklaces.<br /><br />3. **Basic Subtraction**: To find Jumper's weight, solution (C) involves subtracting 52 kg from the combined weight of 60 kg to find Jumper's weight as 8 kg.<br /><br />4. **Shapes and Rotations**: For a shape problem with triangles and circles, solution (E) involves understanding how different shapes fit into a cutout.<br /><br />5. **Counting People and Pets**: Ignoring pets in a lineup leads to the solution (B) indicating 3 people are unaccounted.<br /><br />6. **Pairing Items**: Solution (C) denotes forming 5 pairs of socks by identifying missing numbers that disrupt the sequence.<br /><br />7. **Counting Objects in Overlapping Regions**: Solution (A) involves counting specific flowers without overlapping into other designated areas.<br /><br />8. **Cost Calculation**: By calculating the cost of apples and pears, solution (C) concludes that one of each costs 7 cents together.<br /><br />9. **Gate Problem**: Solution (E) indicates that the mouse can only get through gates 4 or 5, hence these should be closed.<br /><br />10. **Paper Folding Insight**: Solution (B) explains that after folding and cutting a paper, unfolding it results in three separate pieces.<br /><br />The document also continues with similar detailed problem-solving explanations, highlighting useful arithmetic and logical rules. Overall, this exercise not only guides mathematical reasoning but also encourages strategic thinking among young participants.
