10 Free Counting Worksheets for Kindergarten

A Post By: Anthony Persico

Are Your Kindergarten Students Ready for These Fun and Engaging Counting Worksheets (with answer keys)?

One of the most fundamental and important math skills is basic counting. This key skill is first introduced at the pre-school and kindergarten levels and forms as the foundation of all math topics that follow (counting beyond single digits, grouping, addition, subtraction, working with money, etc.).

While there are tons of free kindergarten math worksheets available online, they are not all created the same. Many free worksheets are simply bland and uninteresting, leaving much to be desired and often leading children to start their mathematics journey off on the wrong foot. After all, we never want our students to see mathematics as a dull or boring subject (when it is, in fact, quite the opposite).

However, if you are looking for free counting worksheets for kindergarten students that are actually fun and engaging, then you’re in the right place. In today’s post, you will find 10 Free Counting Worksheets that can be download as pdf files, which are easy to print or share digitally.

These colorful worksheets give students an opportunity to practice and apply their counting skills in the context of “find the fib” or “two truths and one lie,” where students are given three counting examples or diagrams (two of which are true and one of which is false) and must figure out which choice is a fib. Why are these kinds of worksheets so effective for helping students to improve their counting skills? Because they require students to think deeply and actually apply their concepts of numbers and counting in a way that allows them to think critically and mathematically (and have fun at the same time).

Ready to see the results for yourself? Go ahead and download and share a few of our free counting worksheets with your kindergartners and see how they react. If you find the worksheets useful and would like to gain access to all of our kindergarten math activity libraries, you can click here to learn more about our membership program and sign up for a 7-day free trial.

  • While working on these worksheets, we recommend that you encourage your students to explain why they chose a statement as being untrue. You can take it a step further by asking them how they should change the statement to make it true.

  • Whenever you find an answer, ask the question “does this solution make sense?”

10 Fun (and Free) Math Riddles for Adults

A Post By: Anthony Persico

Who says that having fun solving math problems and puzzles is only for children? 

There are over one hundred thousand web searches for math riddles for adults every month, according to Google. If you are one of these individuals searching for fun, engaging, and sometimes brain-bending math riddles and brain teasers made specifically for adults, then grab a pen and paper and get ready for a challenge!

Image: Mashup Math FP

Working on math riddles as an adult is a great way to keep your mathematical reasoning and problem-solving skills sharp while having a lot of fun at the same time. Today’s post shares 10 super fun math riddles for ages 18+ that were created to challenge the adult mind and they are appropriate for individuals ages 16 and up.

Each math riddle is a unique opportunity to apply your problem-solving skills, mathematical thinking, arithmetic, reasoning, and logic. It is recommended that have a pen, paper, and a calculator on-hand when attempting to solve any of these riddles, as drawing a diagram and working out the math by hand can be extremely helpful.

Helpful Advice Before You Begin…

Before you start working on solving all 10 riddles, here are a few helpful hints for overcoming the inevitable moments when you get stuck and/or are considering giving up on trying to solve the problem:

  •  Read each math riddle carefully and think about the problem for a while before doing anything.

  • Utilize strategies such as visualizing, drawing diagrams, and trial-and-error when you don’t know where to start.

  • Don’t get discouraged! When you are struggling and making mistakes, you are in the process of learning. This is called having a growth mindset!

  • Whenever you find a solution, ask yourself “does my answer make sense?”

  • If you are stuck on a problem, take a short break, and do something else like taking a short walk. You’ll be surprised by how the problem will become more manageable when you return.

Practice Problem: Captain Anne’s Coins

In case you are feeling a bit rusty and need a quick refresher on how to go about solving math riddles, below is a bonus practice problem that is worked out step-by-step. You can choose to skip this practice problem if you would like.

 

Image: Mashup Math MJ

 

Here is the problem:

Captain Anne has a chest full of coins.

When she arranges the coins in groups of two, there is one single coin left over. When she arranges the coins in groups of three, five, or six, there is also just one single coin left over. But when she arranges the coins in groups of seven, there are no coins left over.

What is the fewest amount of coins she could have?

 How to solve:

This is a very challenging problem to solve mentally, so using a pen and paper will be a big help (if you are a hands-on learner, you can use real coins to support your thinking and model how to solve this riddle).

In this case, let’s go ahead and create a chart that models all of the possible scenarios, starting with the fact that when she arranges the coins in groups of two, there is one single coin left over. Let’s assume that this is the only true statement that we know, then we could conclude that her total number of coins must be one more than a number that is divisible by two. The possibilities would include:

Possible Coin Totals for Groups of 2: 3, 5, 7, 9, 11, 13, 15, 17, …

You can then go ahead and repeat this process for the statement when she arranges the coins in groups of three, five, or six, there is also just one single coin left over.

Possible Coin Totals for Groups of 3: 4, 7, 10, 13, 16, 19,…

Possible Coin Totals for Groups of 5: 6, 11, 16, 21, 26, 31,…

Possible Coin Totals for Groups of 6: 7, 13, 19, 25, 31, 37,…

Finally, make a list of possibilities for the last statement: but when she arranges the coins in groups of seven, there are no coins left over.

Possible Coin Totals for Groups of 7: 7, 14, 21, 28, 35, 42,…

Now that you have a list of coin total possibilities for each statement, you have to the identify the lowest number that is present on every list. A coin total of 7 is a solid contender because it shows up on almost every list…except for the groups of 5, so the answer must be a different number.

At this point, you’ll notice that there isn’t a number that appears on every list, so you’ll have to start extending them as follows until you find the answer:

Notice that the smallest number that appears on every list is 91.

Final Answer: The fewest number of coins that Captain Anne could have is 91.

Now that you have an idea of how to solve these kinds of math brain teasers, you can try to solve them all! There is a complete answer key at the bottom of this post!

11.) Bonus Math Riddle! : My Three Daughters

A saleswoman knocks on an apartment door and a man answers. They have the following conversation:

Saleswoman: Hello sir, how many children do you have and what are their ages?

Image: Mashup Math MJ

Man: I have three daughters and I will give you a hint to help you figure out how old they are: if you multiply my 3 daughters’ ages, you will get 36.

Saleswoman: That is not enough information!

Man: Well, if you add up my daughters’ ages, the sum is the number of my next-door neighbor’s apartment.

Saleswoman (after looking at the number on the front door of the next apartment): That is still not enough information!

Man: The last hint that I will give you is that my oldest daughter has green eyes.

What are the ages of the man’s three daughters?


ANSWER KEY:

  1. 190 handshakes (19+18+17+16+...+3+2+1=190)

  2. Melon=5, Apple=2, Grapes=3, Lemon=1

  3. Start by completely filling up the 5-gallon jug with water. Next,

    pour water from the 5-gallon jug into the 3-gallon jug until it is completely full (leaving 2 gallons in the 5-gallon jug). Then, pour all of the water from the 3-gallon jug back into the 8-gallon jug. Next,

    pour the two gallons of water in the 5-gallon jug into the 3-gallon jug,

    which would leave it with exactly one gallon of available space. Then,

    completely fill the 5-gallon jug a second time. Finally, pour water

    from the 5-gallon jug into the 3-gallon jug until it is completely full

    (thus filling up the one gallon of available space in the 3-gallon jug),

    which leaves you with exactly four gallons of water in the 5-gallon

    jug! (Here is a video explanation that you may find helpful.)

  4. Oliver started with $9.54. The value of the money can be written using three digits, so it has to be between $1.01 and $9.99. There is only one set of numbers that works:$4.59 + $4.59 = $9.54

  5. 20 Times

  6. 5 cards are missing

  7. 8-4=4, 5+4=9, 0+4=4 (Here is a great video explanation)

  8. The number of eggs must be one more than a number that is divisible by 2, 3, 4, 5, and 6 since each of these numbers leaves a remainder of 1. Therefore, the total is 301 eggs.

  9. 11 Crates Total:
    7 filled with large fruit (7 x 8 = 56 pieces of fruit)
    4 filled with small fruit (4 x 10 = 40 pieces of fruit) So there are 11 total crates and 96 pieces of fruit.

  10. Start by putting three baseballs on each side. If the scales are even, then the baseball ball that was excluded is the lighter one. But if they aren’t even, one side will weigh down while the other side rises up (this is the lighter side). In this case, one of the three baseballs on the lighter side is the light baseball. You can then take these three baseballs and put one on each side of the scale. If the sides are even, then the excluded baseball is the lighter one.
