Including small group instruction in our 75 minute class time is possible! Lesson➡️formative assessment on lesson➡️analyze student data➡️small group instruction as other students work on check your understanding. @ldilworth1 @LizBHolder @TDSBmath

Grade 9 students using algebra tiles as an introduction to collecting like terms. Great way to start from concrete➡️representations➡️abstract and improved engagement as students use the tiles. @LizBHolder @ldilworth1 @TDSBmath

Before jumping straight to the algorithm and you show the visual representation of converting mixed fractions to improper fractions, vice versa, and they yell out “Ooooh, that makes sense!!” 🥹🤩proud of these students! @TDSBmath @LizBHolder @ldilworth1

Implementing our Shaping Algebraic Reasoning PD into the classroom. Students built and walked around trying to determine other groups’ pattern rule. They were able to see the rate of change and constant. Great way to start linear relations! @TDSBmath @LizBHolder @ldilworth1

Day 2 of Leadership in Destreamed Mathematics PD and leaders got to play with algebra tiles to explore how they could use them to collect like terms, add/subtract polynomials, multiply and expand, factor and complete the square. So much fun! @LizBHolder @ldilworth1 @TDSBmath

Day 1 of facilitating with @codru_c on Shaping Algebraic Reasoning with grade 7-10 teachers. Such a great PD on patterning and linear relations. Great activities to bring back to the class and do with students. @TDSBmath @LizBHolder @ldilworth1

Using mini whiteboards as a tool for a whole class formative assessment is so quick and easy to do. Great strategy! @TDSBmath @DownsviewSS @LizBHolder @ldilworth1

Analyzing students' answers on EQAO sample questions from a google form to determine any common misconceptions & to help create small group instruction to work on specific topics with certain students or with the whole class. @LizBHolder @ldilworth1

Had a great time w/secondary math teachers at Northview Heights talking algebra tiles, formative assessments, small group instruction, tracking student data, polypad&desmos. Grateful for the support from admin & dept in continuing professional development.@ldilworth1 @LizBHolder

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.🤩 @ldilworth1 @LizBHolder

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. @LizBHolder @ldilworth1

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 @LizBHolder @ldilworth1 @mervisalo
