ST Math is a visual math program for students in grades PreK to 8. It teaches math with pictures, movement, and puzzles instead of written instructions, so a child can start solving problems before they can read fluently. The star of the program is JiJi, a friendly penguin who guides students through a series of spatial puzzles. It was built by MIND Education, and schools buy it as a classroom program rather than families buying it one child at a time.
How ST Math works
ST Math stands for Spatial-Temporal Math. The idea is simple: children learn math concepts by seeing them and moving things around on screen, not by reading a word problem first. A puzzle might show JiJi standing on one side of a bridge, and the child has to work out how many blocks to move so the bridge reaches the other side. If the answer is wrong, the animation shows exactly what went wrong, so the child can see the mistake and try again.
Each puzzle builds on the last one. The program starts with simple ideas, like counting and comparing sizes, and moves on to fractions, decimals, multiplication, and more advanced topics as the student progresses. There is no timer pushing the child to rush, and the feedback is visual, which makes it a good fit for children who struggle with reading or with traditional worksheets.
Who is JiJi the penguin
JiJi is the penguin mascot of ST Math, and every student gets to know them well. JiJi appears in every puzzle, crossing bridges, climbing towers, and collecting stars. When a student finishes a level, JiJi celebrates with them. The character is more than decoration: because the puzzles are visual, JiJi is the guide who shows the student what to do without a single written instruction. Children often remember JiJi long after they finish the program.
Who ST Math is for
ST Math is built for PreK to grade 8, with the strongest use in elementary school. It is used by classroom teachers as part of the school day, and by homeschool families who want a visual supplement to their main math curriculum. Because the puzzles need no reading, it works well for English language learners and for younger children who are still learning to read. Teachers use it to build number sense and problem solving, and many schools use it alongside a game based program like Prodigy for extra practice.
It is not a replacement for a teacher. It is a practice and concept building tool. A teacher still introduces new topics and talks through the ideas with the class, then students use ST Math to practise what they have learned.
How students log in
Students log in through their school. The school gives each student a login, and students sign in at play.stmath.com or through the school’s own portal, often with Clever or a class code. A parent whose child uses ST Math at school does not need to create an account: the school sets everything up. If a child is using ST Math at home, check whether the school account works from home first, because most school licenses allow home access.
If the login does not work, the first thing to check is that you are on the right page. The student login is at play.stmath.com, not the main MIND Education site. If the password is lost, the teacher can reset it from the teacher dashboard.
What ST Math costs
ST Math is sold to schools and districts as a site license, and the price depends on the size of the school. Families cannot usually buy a single student account directly from the ST Math website. Some districts offer a home version, and a few third party sellers list family access, so check with your school before paying anything. Before a school buys, it is worth asking for a trial, because the visual style suits some children brilliantly and leaves others wanting more variety.
ST Math vs Prodigy Math
ST Math and Prodigy Math both teach elementary math, but they feel very different. ST Math is a calm, visual puzzle program with no reading and no battles. Prodigy Math is a fantasy adventure game where children answer math questions to win battles, catch pets, and finish quests. A child who gets frustrated by reading or who loves puzzles will often prefer ST Math. A child who needs a game to stay motivated will often prefer Prodigy. Many schools use both: ST Math for building concepts and Prodigy for daily practice.
