Pdf Summary

This document presents a set of math problems designed for Math Kangaroo Class Level 3-4, with a subsequent answer key. Here’s a summary of each problem:<br /><br />1. **Temperature Problem**: A scenario is described where the temperature increases by four degrees during the day and decreases by two degrees at night, starting from 70 degrees on a Monday morning. The goal is to determine the temperature on Thursday evening. By calculating the net daily temperature change (+2 degrees per day), the final temperature on Thursday evening is determined to be 80 degrees.<br /><br />2. **Expression Problem**: An expression with operators "" or "–" to be placed between numbers 6, 5, 4, 3, 2, and 1 is presented. With three "–" and two "" used, one must determine which result (3, 5, 7, 9, 10) is impossible to achieve. The answer is 10.<br /><br />3. **Calendar Problem**: In a March with 5 Tuesdays and 4 Wednesdays, one must determine which day could have been the first of the month. The solution indicates that March could have started on a Sunday.<br /><br />4. **Petal Counting Problem**: Given two types of flowers in a garden—lavender with 11 petals each and blue with 5 petals—totaling 65 petals, the task is to find the number of lavender flowers. The answer is 5 lavender flowers.<br /><br />5. **Coin Problem**: Gary has one each of a penny, nickel, dime, and quarter, and must determine which of the given amounts (6, 15, 30, 41, 45 cents) he cannot form. The answer is 45 cents.<br /><br />The answers provided are consistent with logical reasoning and basic arithmetic calculations suitable for children at this level.
