Math u see purchase

Hi! Looking into math u see for my children, ages 7,9,11. When ordering, is it necessary to get the universal set for whatever level they score at, or would the level up set be enough?

Also, my 9&11 year old are visual learners so I’m thinking this would be a good fit for them, any input there? Thanks!

You only need to purchase one set of the integer blocks. Then you’ll only need to order Level Up Set for the other levels your children place at (Instruction Pack, Student Pack, access to the online Digital Pack) Hope that helps! The hands on, concept mastery approach of Math U See has made a huge difference for both of my kids!
