Solve word problems using guess-and-check

This worksheet introduces 4th graders to a problem-solving strategy called guess-and-check. This strategy involves making a reasonable guess, checking if it works, and adjusting it until it is correct. For example:

Two frogs caught 17 flies in a day’s hunt for food. The smaller frog caught 1 more fly than the big frog. How many flies did each frog catch?

 

This worksheet helps 4th graders practice using guess-and-check to solve word problems that involve mixed operations. It also helps them learn how to organize their work and show their steps.

Multi-step-word problems

This worksheet presents word problems requiring more than one step or operation to solve. For example:

Bayron baked 5 trays of 12 cupcakes. He later divided the cupcakes evenly into 6 boxes. How many cupcakes were there in each box?

 

This worksheet helps 4th graders enhance their problem-solving skills and ability to follow multiple steps logically.

Multi-step-word problems: identify reasonable answers

This worksheet asks 4th graders to identify which answers are reasonable for a multi-step word problem involving mixed operations. For example:

Joy’s teacher calls Joy to divide 250,000 by 250 mentally and gives him the answer. Within a short time, Joy told the teacher that the answer was 1,000. Is this answer correct? Why? (Justify your answer)

 

This worksheet helps 4th graders evaluate their answers and eliminate unreasonable ones. It also helps them check their work and avoid careless mistakes.

Learning mixed operations can be fun and easy if you use some of these tips and tricks:

• Use manipulatives, such as counters, blocks, or coins, to model the operations and the word problems.
• Use songs, rhymes, or mnemonics to remember the order of operations and arithmetic properties. For example, you can use the acronym PEMDAS (Parentheses, Exponents, Multiplication/Division, Addition/Subtraction) or "Please Excuse My Dear Aunt Sally" to remember the order of operations.
• Use games, puzzles, or riddles to practice mixed operations fun and engagingly. For example, you can play bingo, crossword, or sudoku with mixed operations problems.
• Use real-life examples or scenarios to relate mixed operations to everyday life. For example, you can use mixed operations to plan a party, budget your money, or cook a recipe.
• Use online resources like videos, apps, or websites to learn more about mixed operations and practice them interactively. For example, you can watch Khan Academy videos, use Math Playground apps, or visit Math Is Fun websites.

Here are some examples with detailed explanations to help you understand how to solve mixed operations problems. You can use these examples as models for your practice.

• Example 1: Sam has 12 stickers. He gives 3 stickers to his friend and buys 4 more at the store. How many stickers does Sam have now?

  Solution: To solve this problem, we need to use two operations: subtraction and addition. First, we subtract 3 from 12 to find out how many stickers Sam has left after giving some to his friend. Then, we add 4 to that number to determine how many stickers Sam has after buying more at the store.

  12 - 3 = 9
  9 + 4 = 13
  So, Sam has 13 stickers now.

• Example 2: Lisa has 15 candies. She wants to share them equally with her 3 friends. How many candies will each person get?

  Solution: To solve this problem, we will use one operation: division. We divide 15 by 3 to determine how many candies each person will get.

  15 ÷ 3 = 5
  So, each person will get 5 candies.

• Example 3: Tom has a rectangular garden that is 8 meters long and 6 meters wide. He wants to plant flowers along the perimeter of the garden. How many meters of flowers does he need?

  Solution: To solve this problem, we need to use two operations: addition and multiplication. First, we add the garden’s length and width to determine how long one side of the perimeter is. Then, we multiply that number by 2 to find out the total length of the perimeter.

  8 + 6 = 14
  14 x 2 = 28
  So, Tom needs 28 meters of flowers.

Now that we have seen some examples of mixed operations problems, it's time to test your 4^th grader’s skills with some practice questions. Ask them to solve these problems on their own before checking the answers.

Problems

1. Ben has a square cake that is 10 centimeters on each side. He cuts it into equal pieces that are 2 centimeters on each side. How many pieces of cake does he have?
2. Mia has a jar of coins that contains 50 pennies, 20 nickels, and 10 dimes. How much money does she have in total?

Answers:

1. To find out how many pieces of cake Ben has, we need to use two operations: multiplication and division. First, we multiply the cake’s length and width to find its area. Then, we divide that area by the area of one piece of cake.

   10 x 10 = 100
   2 x 2 = 4
   100 ÷ 4 = 25
   So, Ben has 25 pieces of cake.

2. To find out how much money Mia has in total, we need to use two operations: multiplication and addition. First, we multiply the number of each coin by its value in cents. Then, we add those amounts together. 50 x 1 = 50
   20 x 5 = 100
   10 x 10 = 100
   50 + 100 + 100 = 250
   So, Mia has $2.50 in total.
