  1. Aunt Jenn

    I got these for my nephew because he really likes math. He prefers being on his iPad or computer, but these cards are cheerful and cute and kept him engaged. His parents (my brother and sister in law) prefer him to have real books and hard copy flash cards so he is not on his iPad and they really love the quality of watermelon math cards and the box! They said it will last generations for my younger nieces who are right behind because it is such a well made product. Thank you!

    My students love these cards!
    I tutor ISEE and SSAT daily and each of these cards contain concepts that my students must know. These creative and colorful cards not only capture my students’ attention, but they also capture their imagination. I have used them with 4th and 5th graders mostly but several 7th and 8th graders have also enjoyed them. A total home run!

    I recently purchased the Watermelon Math test prep cards for my son, who is gearing up for the ISEE. Alongside a prep book, these cards have proven to be an invaluable resource.

    One of the standout features of these cards is their adorable design. The illustrations are not only visually appealing but also serve a crucial purpose in aiding comprehension. Witnessing my son giggle with delight as he engages with the cards on the couch is a heartwarming experience during what could be a very stressful time. The charming imagery truly brings the mathematical concepts to life and helps him form a vivid mental picture, making the learning process enjoyable and effective. My husband is an upper school math teacher and math coordinator and has remarked on the accuracy and effectiveness of the cards’ explanations of concepts and appreciates that our son is using the terms accurately to then explain more abstract concepts.

    Without giving away too much, the inclusion of a “surprise” card put my son over the top! It’s a delightful touch that kept him motivated without sacrificing any educational value, it is quite endearing and really demonstrates the ‘heart’ of the product and its creator.

    Incorporating these Watermelon Math test prep cards into a ISEE preparation routine has not only enhanced my son’s understanding of unfamiliar terms but given him agency – he and his sister have created little games with the cards – for example, they each take turns drawing a card and try to connect an explanation to the previous card. I highly recommend these cards to parents looking for a creative, encouraging and effective way to support their child’s test preparation journey!

    Great product! As a test prep and academic tutor I can attest to the fact that these flash cards make learning these math concepts both more enjoyable and easier. The illustrations are accessible and clever. I’ll be using these cards for years to come, as well recommending them onto my clients.

  5. Brittany Holt

    These are beautifully designed and fun! I bought these for my daughter that takes a little longer to grasp math and I think they will help her a lot.

  6. Leah

    I am a math specialist who works many middle and high school students. I bought these cards because I love giving my students something tangible and visually appealing! The content on the cards is great, and they are beautiful! Such a great investment for any teacher/tutor or parent of students!

    I just took my ISEE test this morning. I used Watermelon Math cards as part of my preparation for the test, and this morning when I felt nervous I brought them along with me on the car ride to have a relaxed review. I really like the artwork because the pictures are cute and fun but also the way the pictures help me to understand and remember is the best. There were some math ideas that I have not learned yet in school, or I learned but did not know the name. For example, I am glad I reviewed this morning before the test because there was a really hard problem about median and mean values and I know I got it right because I saw those cards just this morning! I recommend these cards for their knowledge and also for how they made me feel calm. I am applying for fourth grade.

    These cards are terrific, especially for students who need extra math support. The colorful and kid-friendly design, paired with the digestible break down of key concepts, makes math accessible for even the most math-resistant student! The cards are also very high quality and durable; easy to travel with!

  9. Charlotte O’Connell

    Wow! I just received my set of Watermelon Math cards. They are fantastic! Great Quality, so they will be useful for many rounds of teaching math concepts. Colorful, inspiring and motivating. They will teach learners number types, problems, problem-solving, math vocabulary, functions, and the more subtle concepts that we forget but which are essential to strong math skills. Buy these! Your kids and students will thank you! Or maybe not, but you will know you’ve taken a solid step for their math comprehension.

  10. Alison

    Wow! These cards are amazing! They are perfect for home or school. I really like the clear explanations on the back of each card. The pictures are appealing and colourful. They are a great resource that can be used in many different ways. I am so pleased that I have a set. I certainly wish I had these when I was at school.

  11. Jackie Levine

    Obsessed! Not only is the language easy to digest, the visuals make the concepts easily understandable. Therefore easier to master mathematical concepts. Thank you Watermelon Math!

  12. Natasha L

    These cards are amazing! The examples are thoughtful, fun, and easy to understand. All of my students loved them. Yesterday we played taboo with them and the engagement we saw was amazing! They were giving such detailed examples of the different vocab terms. I want more cards for middle school topics!! They’re so good! I plan on using these over and over again in whole group and small group. They’re good reminders for the many topics we teach in math. Plus, I love supporting a small business!

  13. Christine Feight

    These cards are high quality, visually appealing, and super helpful! As a tutor, I’ve used these cards to help students prepare for the ISEE exam, but they can be helpful for any student in intermediate/middle grades. I always test out new products to find the best resources for my students, and this one goes above and beyond the quality you see in other cards and prep materials. You can tell a lot of thought went into their creation, and they were developed by someone who has the students’ best interest in mind. I look forward to seeing future products!

  14. Shan J

    My daughter is gearing up for the ISEE, and these cards have been an invaluable resource alongside her prep book. The explanations are clear, and the illustrations (beyond cute btw!!!) make the concepts memorable. She even enjoys using them to play games with her sister!

  15. Vicki R

    These cards are beautifully designed and fun! They’re perfect for my son who struggled with the standard textbook for ISEE prep. The pictures and explanations are clear and engaging, and I think they’ll really help him understand the concepts. I also appreciate all the little details that went into this product from the texture of the cards to the design and of course, the way complex concepts are broken down to simple fun nuggets!
