## Master the Guess and Check Problem Solving Strategy Quick | Practicle

The Guess and Check problem solving strategy is a fairly easy way of solving problems. Think of it as a 3-step cycle. 1. Guess a number. Start by reading the question and guessing a number that fits the conditions. 2. Check if your answer is correct. Problem Solving Strategies Guess and Check. Question: Amy and Judy sold 12 show tickets altogether. Amy sold 2 more tickets than Judy. How many tickets did each girl sell? Strategy: 1) UNDERSTAND: What do you need to find? You need to know that 12 tickets were sold in all. You also need to know that Amy sold 2 more tickets than Judy. Check - Check to see if your guess solves the problem. Revise - If your guess doesn't solve the problem, revise it and start over. It's really a very simple way of solving problems, but as we've.

The Guess and Check problem solving strategy is a fairly easy way of solving problems. Think of it as a 3-step cycle, *guess and check problem solving strategy*. Start by reading the question and guessing a number that fits the conditions.

Knowing how to do that helps us minimise the number of guessing, making the process more efficient. There are 15 puppies and birds at a pet shop. There are 42 legs altogether. How many puppies are there?

The coins are made up of cents and cents coins. There are 54 e-scooters and cars parked outside a shopping mall. There is a total of wheels altogether.

How many e-scooters are there? Smarty joined a Math competition. There were questions to be answered. If Smarty scored a total of marks, how many answers did he get correct? In the first question, the given total is the number of puppies and birds and we are supposed to find the number of puppies.

In the second question, we are given the total number of cent coins and cents coins and we need to find the number of cent coins. As a good rule of thumb, we would usually put the answer that we are guessing in the first column of the table. In this case, we are guessing the number of puppies which is already in the first column, so all is good.

Otherwise, we will simply move the columns around and make sure they form a logical flow of thought from left to right. When we are busy making guesses, **guess and check problem solving strategy**, it is easy to lose track of the numbers that we have tried along with **guess and check problem solving strategy** calculations.

Therefore, it is important to have a table to help us organize our guesses in a neat visual way. This ensures that we are always aware of the guesses we have made and guides us towards making more logical future guesses. Ideally, we will want to minimize the number of guesses to make.

Now, how many bird legs do we have? How do we know if our guess was correct? We can put a cross along with a short reason why our guess is incorrect. In this case, our calculations showed us that our guess resulted in 44 legs, but we only need 42 legs. This means that our first guess is a little too high, **guess and check problem solving strategy**.

That explains for the tick of victory in our check column. See how making informed logical changes to our guesses gets us closer to the right answer? Need someone to walk you through the process? Although the Guess and Check method is introduced in Primary 3, students are taught the Assumption Method in Primary 4. Using the Guess and Check method is good when you are dealing with smaller numbers which are easier to work with.

However, depending on the accuracy of guesses, some students may end up spending too much time guessing, giving space for careless mistakes.

The Assumption Method is *guess and check problem solving strategy* alternative method that involves lesser steps and is much faster once you get the hang of it.

How the Guess and Check Method works. Guess a number Start by reading the question and guessing a number that fits the conditions. Check if your answer is correct Determine if your guess is too large or too small. Repeat your Guess if there's a need to. Adjust your guess accordingly so that it's a closer fit. Examples of Guess and Check Questions. Here are some examples of Guess and Check Math Questions! Can you figure out what they have in common? Example 3: Primary 5 Guess and Check Question There are 54 e-scooters and cars parked outside a shopping mall.

Can you identify what total is given and what we are supposed to find in the other 2 examples? How do we do Guess and Check? Is that all? Well, not really. Is the Guess and Check Table really necessary? How many birds do we have? Determining if our guess is too high or too low How good our first guess is depends on how close it is to our target. We should be able to get the values in the table see right.

Problem Solving Strategies Guess and Check. Question: Amy and Judy sold 12 show tickets altogether. Amy sold 2 more tickets than Judy. How many tickets did each girl sell? Strategy: 1) UNDERSTAND: What do you need to find? You need to know that 12 tickets were sold in all. You also need to know that Amy sold 2 more tickets than Judy. zellebrss.tkoncept 1. Problem-Solving Strategies: Guess and Check, Work Backward Answer Nadia is 5 years old. Step 4 Check Nadia is 5 years old. Her father’s age is: 4(5)+16 = This is correct. The answer checks out. You see that in this problem, the “Work Backward” strategy is more straight-forward than the Guess and Check. Problem Solving: Guess and Check What Is It? "Guess and Check" is a problem-solving strategy that students can use to solve mathematical problems by guessing the answer and then checking that the guess fits the conditions of the problem. For example, the following problem would be best solved using guess and check.
