Grab your conversation hearts and practice math skills with these 10 valentine math activities. They include measurement, adding, equations, comparing fractions, and more.

“What did you get?” says one little voice with their head buried in a white bag with glitter and white hearts all over.

“Wow! Look at this card!” exclaims another pulling out a small rectangle with their favorite character on it.

“Yes!!!” says another excited voice as they pull out a yummy piece of candy.

Valentine’s Day! It is such a fun holiday for little ones as each child passes out the cards they painstakingly choose and then gets to dig through their bag to see what they have received.

Yes, this time is so much fun, and you can easily tap into that to make math fun too.

To celebrate this fun day, I will be sharing seven new posts that can be used to make math special! So grab a bag of conversation hearts and let’s get learning with these Valentine Math Activities.


This is an eight day series that will begin Monday, February 5th. Check back each day for the new post!!

Adding Within 10

Next, we have a fun hands-on adding activity. By second grade we want our little ones to know their addition facts, but there is so much work that needs to be done before the second grade for this to happen.

Children need to be playing with manipulatives to figure out all the different combinations to equal certain numbers. And this activity has kiddos doing this with conversation hearts.

Lines and Angles Vocabulary

Part of a geometry unit is to learn vocabulary words such as parallel lines, perpendicular lines, and right angles. These task cards have children using conversation hearts to create obtuse angles, rays, and more. There is one set that has the lines drawn on them, and all the children have to do is place the conversation hearts on the lines. The other set is blank allowing the children to design their own using conversation hearts.

Determine the Unknown Whole Number in an Addition or Subtraction Equation

Even for my guy who just gets math, this was a little difficult. Normal his mathematical mind does not need manipulative to solve problems, but in this case….they were needed.

This activity provides children with an equation that has a missing number. Using conversation hearts and ten frames, our precious ones figure out what that missing number is.

These task cards are a great way to develop the math sense they will need for algebra!!

Repeated Addition With Arrays

Once again, grab some conversation hearts to explore multiplication. There is so much learning in these simple task cards.

First, and most obvious is the concept that multiplication is repeated addition.

Next, a foundation is being laid down regarding arrays.

Finally, the concept of area is introduced.

NonStandard Measurement

This simple activity has children measuring Valentine related objects using conversation hearts!! You can keep it at that, or add graphing skills, and then vocabulary word such as mean, median, and mode.

Determine the Unknown Whole Number in a Multiplication or Division Equation

Multiplication and division can be a struggle for some little ones. This activity has them exploring the relationship between the two by making groups and dividing up the hearts. I’ve kept the numbers small so the concept can be developed without a ton of counting happening.

Comparing Fractions On a Number Line

One way to teach comparing fractions is to relate the fraction to one-half.

“Is this fraction greater or smaller than one-half?” is an awesome question to use when comparing fractions.

These task cards have children placing conversation hearts on a number line to determine if they are greater than, equal to, or less than. One fraction will be greater than one half, and the other will be less than so that children can practice comparing fractions to a benchmark fraction such as 1/2. 

Dividing Fractions with Models

Did you know that you can model dividing fractions? You can, and these printables will help you!

See how to use them on my facebook page!!
