I absolutely LOOOOOVE Prufrock Press! They are the go-to publishing company for all resources/text in regards to Gifted Education/Advanced Learning/Twice-Exceptional students. Teacher-friendly, jam-packed with differentiated/enrichment/supplemental materials, available manipulatives, informative reads for educators, as well as units for all subject areas, Prufrock has them all. I especially love the 'A Mathematical Mystery Tour,' 'Brain Food,' 'Vocabulary Ladders' and the 'Science Sleuths.' They definitely engage the students and the ideas in these resources are fantastic. +manipulatives +extensive GT resources read more
