I use the resources primarily for students with learning difficulties, and on the autism spectrum for extra practice and during independent centers. The resources are engaging for all the students. The worksheets are printed and laminated so the students were able to use a dry erase marker to circle the answers. This also allowed a quick clean up and ready for another group.

Been using Skoolmaths with my fifth grade class. The resources are great! My students are always fully engaged with the fun drag and drop interactive activities. A great way to practice their maths skills. Thank you!
