Despite today's winter weather, teachers in North York #TDSB had an energy-filled Day 2 of Building Foundational #Math Skills! We analyzed the lasting usefulness of Up & Over 10 & Constant Difference & played games to promote various (+/-) strategies. @tdsbmath.bsky.social @mervisalo.bsky.social

#Fractions through Paper folding today in the 4/5 class @Flemington PS. This hands-on activity was engaging and super fun for all students; at the same time: a great assessment opportunity for the teacher! @tdsbmath.bsky.social @mrjasonto.com @mervisalo.bsky.social

Every time there’s been an A-ha moment, an understanding of the math concept as a result of work with concrete objects, I thought of Maria #Montessori’s belief from almost 100 years ago: a child’s “hand activities” and “psychological development” are so closely entwined. @tdsbmath.bsky.social
