What ages and grades is it for?+
K12 Crafter covers Kindergarten through Grade 5, roughly ages 5 to 11, from counting all the way to fractions, decimals, and geometry.
Do I need the internet to use it?+
Not for the worksheets. Print the packs once and your child can practice off the screen any time. The practice app needs a connection for instant feedback and saving progress.

You can start for free. Prices are shown in TZS and you pay securely with Paystack, the payment option Tanzanian families already use. Worksheet packs are a one time purchase per grade and the app is a family subscription.
Is it safe for my child?+
Yes. You own the account and your child is a simple profile under it. There are no ads and no third party trackers in the kids experience.
