Key takeaways
- • Summer slide happens to everyone, but its effects can be lessened by review during the summer.
- • There are fun and exciting 4th grade math activities students can do no matter where they are, whether they’re indoors or outdoors.
- • The internet is a good resource for online math games and other resources during the summer months.
Fear often comes from a lack of preparation. That first day of 6th grade may look scary from where you are now, but with the right preparation during the summer, the start of 5th grade math can feel easy!
The first step to preparing is to avoid the summer slide.
No matter how good a student you are during the year, no one is immune to forgetting a few things during the summer. But with the right activities, you can review everything learned during the school year and prepare for what lies ahead in September.
The following 10 summer math activities for 4th grade make math fun, helping students stay sharp during the summer break!
5 Summer Math Outdoor Activities
The following five summer math activities for 4th grade can be played outside.
1. Conversion Quiz Basketball
Have fun with fraction, decimal, and percentage conversions with this fun basketball game! You’ll need at least two players for this game: one caller and one shooter. The caller calls out fractions, decimals, or percentages, and the shooter has to convert them.
For instance, if the caller says “25%,” then the shooter should say “.25” or “¼.”
If they get it right, they get to shoot the ball. The shooter gets 1 point for every correct answer, and another point for every basket.
If there are multiple players, the player who earns the most points wins. If there is only one player, set a timer so they can try earning as many points as they can within a set time frame.
2. Blindfolded Directions
For this activity, you’ll need a flat, open area, such as a schoolyard, backyard, or park.
Start by having one player put on a blindfold. Next, mark an ending position or goal—this is the location the other players will try to guide the blindfolded player to.
Then, the other players can take turns giving the blindfolded player directions using numbers of steps and angle measurements! For example, “Walk five steps forward then turn 90 degrees counterclockwise.” (Avoid saying “left” or “right.”)
To make this activity more of a challenge, you can set up obstacles along the way to the ending position.
3. Hunting for Angles
This activity can be done anywhere! Using a protractor, participants can explore their surroundings and measure any angles they see. They can start by identifying the angles as either acute, right, or obtuse, and can then take things a step further by measuring the exact angle with their protractor.
4. The Multiples Ball Game
To play this game, first pick a one-digit number. Players can then toss a ball back and forth, counting up by multiples of the number they picked each time they catch the ball.
For example, if the number picked was 4, the players should say “eight,” “twelve,” “sixteen,” and so on as they toss the ball.
Players should try to toss the ball at least 10 times without dropping it! If they can do more than 10, even better!
5. Water Balloon Target Practice
Set this activity up by filling some water balloons and carefully writing equations on them. Then, on a wall outside or a piece of pavement, draw a target with different sections labeled with numbers.
These sections can look like anything—think polkadots, a grid, random shapes, or anything else that looks good to you. Just make sure the sections are around the same size.
Players can then pick up a balloon and throw it at the number that correctly solves the equation written on it. If they hit the correct number, they get a point!
5 Summer Math Indoor Activities
For days stuck inside, 4th graders can use the following five indoor math activities to have fun and boost their math skills.
1. Blackjack
This classic casino game is a great indoor math activity to improve 4th-graders’ math skills.
To play, the “dealer” gives themself and the player two cards. The player’s cards should both be face up. The dealer’s first card should be face down and the second should be face up.
After looking at the face-up cards on the table, the player can then either “hit,” meaning the dealer places another face-up card on their stack, or “stand,” meaning they don’t want any more cards.
Once the player is happy with their hand, the dealer reveals their face-down card. Whoever’s hand is closer to (but stayed under) 21 wins the round.
Playing Blackjack allows players to strengthen their mental arithmetic, probability, and comparison skills, all while having fun!
2. Multiplication War
In the traditional game of War, two players split a deck of cards, then “battle” each other by flipping over the top card of their deck. The player with the higher-value card wins, and play continues.
In Multiplication War, players battle each other by multiplying the values on the cards they flip over. For example, one player’s card may be a 3 while the other player’s card is a 9. The first player to shout “twenty-seven” would win the battle.
You can count the values of face cards as: Jack = 11, Queen = 12, King = 13, and Ace = 1 or 14.
(You can leave out the face cards for easier gameplay!)
3. Fraction War
Similar to the previous activity, Fraction War is a twist on the classic War card game. But this time, instead of making greater-than or less-than comparisons between whole numbers, players compare fractions!
During battles, both players play two cards. The first card is the numerator, the second the denominator. Whoever has the larger fraction wins the battle!
4. Board & Card Games
The classic dice game Yahtzee, the card game Five Crowns, and the board game Mancala are all good examples of games that combine strategic thinking with math, making them just as educational as they are fun!
Most games require some form of math, even if it’s something as simple as adding up a dice roll. Besides Yahtzee, Five Crowns, and Mancala, try playing Set (pattern recognition), Blokus (spatial awareness and geometry), and Shut the Box (addition).
In these games, math is more a means to an end—it’s definitely there, but it’s not too prominent. If you’re looking for games where math is the focus, try these:
- Skyjo (card game): addition & subtraction
- Dice of Fury (dice game): addition & subtraction, pattern recognition
- SMATH (board game): basic algebra
- Fractions Wild! (card game): fractions
- Exact Change (card game): money counting
- Over Under (card game): measurements & estimation
If you’ll be spending time indoors this summer, these games are all good ways to pass the time!
5. Online Math Games
Don’t sleep on the internet! It can be an amazing resource for accessible and entertaining educational games. A simple online search for “4th grade math games” will bring up hundreds of games covering a variety of topics, from addition, subtraction, multiplication, and division to fractions and more!
For more structured learning, pick an online math program or website, like DreamBox, to follow a specific online curriculum while still having fun and exploring new games and activities.
