Reading - bit.ly/2QBFWVF (See my IG highlights to get for free: / akeebamaze ) *
This reading program is great when starting out, but don't use it longer than a year for advanced/gifted students as it will be too easy for them.
Math (free) - bit.ly/3bh9HmP
Math (paid) - bit.ly/2WJ670R
Science - bit.ly/2Uw969T
Social Studies - bit.ly/2WBmlJ7
