Start with one question
Focus on the skill in front of you. There is no timer or race to finish, so you can take time to read and think.
K–8 mathematics · One idea at a time
Online math practice
at your pace.
Whetta is an online math practice app for kindergarten through eighth grade. Fresh questions, helpful hints, and room to try again help learners take their next step.
The sample needs no account or payment card. Family access to Whetta is by invitation.
Space to think
Practice the idea. Understand the answer.
Ask for a nudge
A hint helps you find a starting point. If an answer doesn't land, use the explanation to understand the relationship and try again.
Return to the idea
In family practice, fresh questions give learners another chance to use a skill. Parent controls manage saved practice and progress.
A small beginning
Try two math practice questions
Take your time. Think through each question, then open the explanation to check your reasoning.
Ratios · Comparing groups
Which group comes first?
A bowl has 4 apples and 6 pears. What is the ratio of apples to pears?
Show a hint
The order of the words matters. Count the apples first, then the pears.
Show the answer and explanation
The ratio is 4 : 6, or 2 : 3 in simplest form. For every 2 apples, there are 3 pears. A ratio of 4 : 10 would compare apples to all the fruit, which answers a different question.
Fractions · Equal pieces
How many pieces fit?
A ribbon is 3/4 of a metre long. You cut it into pieces that are 1/8 of a metre each. How many pieces do you get?
Show a hint
Write three quarters in eighths. How many eighths fit into each quarter?
Show the answer and explanation
You get 6 pieces. One quarter equals two eighths, so three quarters equals six eighths. Dividing 3/4 by 1/8 asks how many one-eighth pieces fit in the ribbon: 3/4 ÷ 1/8 = 6.

For families
Before you start
Is Whetta free to try?
The public ratio sample is free and needs no account or payment card. It includes three fixed demonstration questions. Access to the family math practice app is by invitation; request an invitation on the homepage.
Which grades is Whetta for?
Whetta focuses on K–8 mathematics. The public interactive sample introduces Grade 6 ratios: comparing two groups, keeping their order, and comparing one group with the total.
Can my child practice math online without downloading an app?
Yes. Whetta's web app runs in a browser, and you can open the public sample directly from this page.
Does the free sample save my child's answers?
No. The ratio sample does not create a saved learning record. For family practice, parents manage child profiles and saved practice through their account. Explore the parent view.
