Learning with Sticky Notes and Yarn

This hands-on review idea comes from Hands On as We Grow! (They did sight words). You can use it to assess students on any topic: operations and algebraic thinking, synonyms and antonyms or food chains (just to name a few). The food chain activity doesn't even need sticky notes (just print out images). The possibilities are endless with yarn and tape!

Soda Math - Kid Style

Split students up into groups. Give each group some sugar packets to experiment with multiplication strategies. How many packs do they have? Tell them that each pack has 4 grams of sugar. How can they figure out how many grams of sugar they have?

Once they have figured it out, give each group a different can of soda. Can they figure out how many packs are in their can of soda? First, have them estimate! Then, they solve! They could use their multiplication strategies. More advanced students might figure out that they can get their answer faster by dividing. Students collaborate and problem solve to get the solution! Was their estimated number close to the final result?

Dice Roll Division

This fun division game comes from Learn-With-Math-Games! Kids get 20-50 counters (or other manipulative: dried beans, cheerios, etc.). They roll (1 or 2) dice and divide the number of counters they have by the number the dice lands on. For example, there are 20 counters and the child rolls a 3, he creates three groups using his 20 counters. Whatever is leftover is the remainder. The child keeps what is leftover (2 counters). On a sheet of paper, he writes down the answer: 6 with a remainder of 2 (6 r 2). He has 18 counters left to play with. Then, the next person goes. If a player rolls a numeral that is bigger than the number of tokens left to divide, he loses his turn (ex: player has 4 tokens left and rolls a 6). The player can't create 6 groups using 4 tokens.

Fruit Snack Math

The wrapper tells you how many fruit snacks are in the bag. Estimate how many of each flavor is in your bag before opening it.

Write a fraction for each flavor. Then, graph your flavors. How did your bag compare to your peers? Do you think that the flavors are evenly distributed?

Lay your fruit snacks out an a straight line. Can you find something that is the same length? (measure)

Find a friend and compare your fruit snacks. Who had more cherry? Did you have the same amount of cherry? Compare each flavor using greater than, less than, or equal to signs.

Create a multiplication array with your fruit snacks. Then, practice division. How can you divide your snacks evenly if you shared your bag with your mom and dad?

Write addition and subtraction number sentences: What is the sum of your strawberry and grape (2+3=5)? If you ate all of your orange and lemon, how many fruit snacks would be left (12-5=7)?

Make different patterns with your colors. Did you have any difficulty because of the colors in your bag?

100 Chart Games



1. Prime Number Hunter - Who can find all the prime numbers the fastest?! - Education.com
2. Factors and Multiples - 2 players: 1st player puts a marker on the number 50. Then next player puts a marker on a factor or multiple of 50. Kids continue to take turns finding factors or multiples of the number the previous player put their marker on. The player who fills the board first wins! - Nrich
3. Puzzling! - Cut up a 100 chart into a puzzle!
4. Secret Picture! - Kids answer number sense questions, follow a color key, and figure out the hidden image! Have students make their own for a friend to solve! (see image below)
5. 20+ games using a 100 chart! - Let's Play Math!
Note - You can find printable 100 charts online. The one I used is from Madame Parker's Grade One

GCF and LCM

In addition to the factoring tree, try these two different ways to find the greatest common factor and least common multiple by Rebecca Newburn!

"Indian Method"
Kids figure out what number goes into each of the digits (should be the same numeral). They write the number along the side line to the left. They continue this process until there is no common divisor. Then, they multiply the numbers (common divisors) on the left and presto - they have their GCF! To find the LCM, they create an "L" around the numbers to the left and the bottom row (see example below). They multiply and find the least common multiple, easy! This method makes it a cinch for students to find the GCF and LCM of more than 2 numbers. Click here for a video!












"Birthday Cake Factorization" and Venn
Kids create tiers for their "cake" (see example below), when they reach the number 1, voila, they have a candle! Then, using their "cakes," they can figure out the greatest common factor and least common multiple with the help of a venn diagram. Click here to see the process in action! Also check out Rebecca's other videos for making math simple!

Long vs. Short Division

Having trouble with long division, simplify it! This simple trick comes from Math Guide
Short Division example below: 
1. 6 into 25 = 4
2. 1 left over, draw it in front of the 3
3. 6 into 13 = 2
4. 1 left over, draw it in front of the 2
5. 6 x 2 = 12, No remainder!

Picnic Fractions




For a math station, set up a picnic basket of food (images for kids to cut). Students plan a picnic, create food fractions (use a ruler and scissors), glue food fractions on a paper plate, and write the fraction for each item. Kids are not only practicing their fraction skills, but division too!

Twister Place Value and Learning Games

I was inspired by Raki's Rad Resources Number Creation, so I made Twister Place Value for a math station, so kids could play independently. You need at least three players (one person spins the spinner and calls out, while the other two play), the game Twister, and numbers to stick on the mat. Kids follow the spinner (example right hand red). They choose a number on red to place their hand. Just like original twister, if right hand red is called out again, they must choose a different red numeral to place their right hand on. Kids spin the spinner and choose a numeral four times to create their final number in the place value of 1,000. After they have four numbers, they write their numbers down and try to create the largest numeral. For example, if they have 5, 8, 0, 3, they would write down 8,530. After they write down their number, then they must write the number in expanded form (8,000 + 500 + 30 + 0). Then, they compare their number with their opponent's using greater than, less than, or equal to signs. Whoever has the greatest number wins!

Beginner's Division

Division doesn't have to be so complicated! Have kids practice equal division by dividing snacks, crayons, and even friends into groups.

Let's Roll!



Roll a hula hoop down the pavement in a line. Mark the starting line and draw a line from the starting point to where it stopped. Now, use your measuring skills to figure out how many times the hula hoop rolled in a complete circle! Cut a piece of string the size of the hula hoop's circumference. Hold one side of the string and lay the other end around the hoop until it meets the side you are holding. The string represents the circumference. Use a ruler and measure the piece of string to find the circumference. Next, measure the line you drew on the pavement to figure out how far the hoop traveled. To figure out how many times it rolled divide the distance by the circumference. 

For smaller kids, you can simply use your circumference string and make marks on the line you drew. Count your marks. Your marks represent one full hoop. How many times did your hoop roll?

Can't find a hula hoop? Learn how to make one here!

Kid Calculator

Draw an oversized calculator to help kids with math! Kids throw a stone on a number. Then, they have to figure out how to make the number (addition, subtraction, multiplication, or division). For example, the stone lands on 8. You jump on 8. Then, you hop to 4, hop to the multiplication sign, jump to 2, jump to the equal sign, and hop back to 8. 

Excuse the 3 2 1 line (it's written backwards), my bad!

Wet N Wild Math



Water Balloons
1. Division - Count up how many water balloons you have in all. Then, figure out how many you and your friends will get.

2. Fractions - Choose what color balloons you would like and figure out the fraction for each color.

3. Addition - Water balloon bullseye! Hit the target, aiming for the sections worth the most points. Keep track of your score. Make sure you watch where your balloon bursts! Also, you probably want to tape the target marks. Otherwise, your board will wash away!

4. Geometry - Measure your balloon's circumference. What is the diameter and radius of one water balloon? Also, measure the length and width of your balloon. Can you figure out the volume?

5. Measuring - See who can throw their water balloon the farthest. Measure where the balloon lands.
