Mathematics in Context
V-Patterns; Beams; Hair & Nails
V-Patterns, Beams, Hair & Nails:
This video lesson shows an informal preformal formal progression of algebraic
thinking from grade 6 to grade 8. Three middle school teachers work together
to make math accessible and understandable to students at all levels,
one of the major goals of this curriculum. In the grade six lesson, "V-Patterns,"
students are introduced to basic algebraic thinking by analysing the flight
pattern of geese. In grade seven, students explore beams used at a construction
site to discover patterns and express these patterns with formulas. Finally,
in grade eight, children represent hair growth using three different representations:
linear equations, tables and graphs. Throughout, students are discovering
relationships and making generalizations using algebraic thinking.
