Easiest Ways to Solve 3rd Grade Math Problems With Examples

Parents of 3rd graders often ask: Why do students get stuck or lose confidence, even after hours of video lessons or worksheets?

3rd grade is a huge turning point in math. I see it happen every year: kids go from just learning basic math facts to actually using math to figure out complex problems.

I recently sat down with expert Cuemath tutors to find out exactly where 8-year-olds get stuck. The main issue? Moving from counting on fingers to doing math in their heads is a massive leap that trips up even the smartest kids.

We are going to show the easiest ways to solve 3rd-grade math problems with the help of Cuemath visuals and simulations and the absolute best resources available.

Where Do 3rd Graders Struggle?

According to Cuemath tutors, 3rd-grade students primarily struggle because they must read and solve word problems at the same time. If they don’t understand the question, they may lose focus or give up.

1. 3rd Grade Math Problems are Difficult to Visualize

Consider this common 3rd-grade math problem:

Mia has 12 apples. She gives 5 to her friend. How many does she have left?

If reading and comprehending this feels tough, your child might lose interest before they even get to the math.

2. Distracting or Irrelevant Numbers

Some 3rd grade math problems often seem to be piling on the extra information:

“There are 10 pencils, 7 pens, and 8 crayons in a box. How many pencils are there?”

It is easy for a child to add all the numbers instead of focusing only on pencils.

3. Multi-Step Problems Introduce More Complexity

3rd-grade math often asks for two-step thinking:

“Jessie has 12 candies, buys 8 more, then gives 5 to a friend. How many candies now?”

Kids interpret one step, get confused at the second step or mix up the order.

Tips for Solving Complex 3rd Grade Word Problems

When children see a block of text, panic often sets in. Here are my top tips for solving complex 3rd-grade word problems:

1. The CUBES Method: Teach them to Circle numbers, Underline the question, Box the math action words (like altogether or left over), Evaluate the steps, and Solve.
2. Draw it out: Encourage them to sketch the scenario. Visualizing the story removes the intimidation factor of the text.

Let’s start by moving the clock ahead to 10 minutes (5+5 each time)

Now move down to 1 minute each

Minutes passed since 6 o’clock

= 10 + 1 + 1

= 12 minutes

So, Owlie finished coloring at 6:12

Data Handling Math Problems for 3rd Graders

Question 9:

The bar graph shows the different types of birds that Mindy saw in a jungle.

What is the difference between the number of Pelicans and Flamingos that Mindy saw?

From the bar graph we can see,

Number of Pelicans = 8

Number of Flamingos = 18 (The bar is plotted between 16 and 20, so half of this is 18)

Difference = Flamingos minus Pelicans

= 18 - 8

= 10
