Check out @profkeithdevlin's thoughts on #PISA and the Common Core State Standard for Mathematics, new from #MathValues: https://t.co/sFM0ZiXilt #CCSSM
@msmackeymath I stopped teaching the difference between a relation and a function altogether, in response to it being removed from #CCSSM. The discussion on page 8 of this document takes up this question: https://t.co/d1CPQi4Pak
This youngster is going somewhere! Explaining mathematics! Notice how he understands how 0 and 1 work. The identity properties are not trivia, but huge. #iteachmath #CCSSM
@mathgrrl @mrdardy @dandersod Bingo. @wgmccallum’s work on mindful manipulation (e.g., https://t.co/9P5qCFQVva) was illuminating for me. Also Al Cuoco et al. on mathematical habits of mind.
A big reason “simplify” was rightly excluded from the #ccssm #commoncoremath. @IllustrateMath #MTBoS #iTeachMath
Kindergarten friends brought in 3D shapes from home then they sorted them today! Look how many cylinders & spheres they found! #ccssm #ctreg14 #kindergarten
Does anyone know why area and perimeter and like topics fall under Measurement & Data in elem standards, but surface area, volume, etc., fall under geometry later on? Why isn't measurement & data strand focused only on categorical and measurement data? #mtbos #iteachmath #ccssm
Grade 8 math team collaborates in writing student-facing learning targets that address relational and computational thinking. #CCSSM
Just a quick brag with beautiful work ~ today our students demonstrated their creative story contexts to show understanding of the division interpretation of a fraction https://t.co/VXfQxV6nDh.3 #ccssm #bigkatmath
Ss connect division as multiplication- commutative property- to check division thinking. #NVCoreAdvocates #coreadvocates #iteachmath #ccssm
Ss making connections with a whole number divided by a unit fraction. #NVCoreAdvocates #coreadvocates #ccssm #iteachmath
Expert mathematics educator @steve_leinwand conducts a #demonstration lesson for early elementary teachers on exploring the ordering of 3 lengths using indirect comparisons #ccssm #mathinstruction #embeddedPD #teacheraslearner
It's a great day to be a Leatherneck. Today we are learning what multiplying fractions means. #iteachmath #6.NS.1 #CCSSM (#2 of 2)
