A7. Notice names with numbers attached. Names seem to be in alphabetical order. Wonder if there is a pattern or reason for numbers connected to each name. #ElemMathChat
A5: We did frayers a lot. Most of the time on a shared slide so kids could "cheat" and see each other's work. Review I used Gimkit to make it fun. Kids would also create the Review questions so they had to write/punctuate/spell correctly. #ElemMathChat
A4: I used to use pictures to generate 8 parts of speech and writing. Estimysteries pictures, collections/jars could easily be re-used for writing/storytelling #ElemMathChat
A2: I notice some of these jumpvright put as familiar. 26 letters of alpha, 7 days of week. But others are less known. #ElemMathChat
A1. Scrabble was always a big ine. I remember the decipher code puzzles too. #ElemMathChat

@drnickinewton.bsky.social · last yr.When kids subtract from teen numbers: 🖐 Feel it (manipulatives) 👀 See it (take ones away) ✏️ Symbolize it (write equation) That hands → eyes → brain path makes subtraction stick! #primaryteachers #primaryschool #firstgrade #firstgradeteachers #secondgrade #subtractionstrategies #homeschooling
Today I helped some teachers come to grips with the fact that their 4th grade math textbook has many lessons that are NOT 4th grade standards. Not only does the book NOT advocate good teaching...it is also teaching the wrong stuff. #CMCforQualityMath #UseHQIM
