Day 1 of Shaping Algebraic Reasoning allowed teachers to engage and play in the math. We built patterns with tiles and saw how this can help our students see the multiplier&constant, determine equations and make predictions.

šŸ’„ Fraction Tiles are an excellent tool for connecting the Concrete, Representational, and Abstract stages when adding fractions with unlike denominators! #math #education

When the correct answer isn’t 22, but I wouldn’t have known that if I didn’t use the mini whiteboards a a tool for assessment. This helped my partner teacher & I know that this was a question we needed to take up with the class. Jason To is chillin’ on BlueSky (@mrjasonto.com) Liz Holder Lisa Dilworth Mervi Salo

Gr. 4/5s @TDSB Flemington PS practised equipartitioning a length w/ the Unit #Fractions Paper Strips task. This hands-on activity was engaging and super fun for all students & a great assessment opportunity for the teacher! Mervi Salo Jason To is chillin’ on BlueSky (@mrjasonto.com) Liz Holder

Awesome gr9 Ss solves 2x+3=x+1 w/ algebra tiles. Day before we used tiles to add&subtract polynomials. Then a bit of direct instruction for solving equations & off they went! I didn’t even do an example for multi step&they figured it out themselves. Liz Holder Lisa Dilworth

The importance of collecting ongoing data w/ formative assessments. We were keeping our eye out on these students,taught them algebra with algebra tiles &were able to move them forward. Still have more work to do but happy to see these students succeed.🤩 Lisa Dilworth Liz Holder

Loved seeing the ten sticks being used today at Thorncliffe Park TDSB with gr1/2 student during student math interviews. Such an easy way to practice splitting by grouping tens together! No more finger counting! TDSB Mathematics & Numeracy Lisa Dilworth Liz Holder NadiraPersaud-FOS14/LC2
