Arts
Counting Beats: Note Values and Full Measures in 4/4
Students learn how many beats each note and rest gets in 4/4, add up written rhythms to see which measures are full, and fix the ones that are not.
Mathematics
Expressions and One-Step Equations: Words to Symbols
Students match word phrases to algebraic expressions, evaluate an expression, and solve one-step equations from word problems.
Technology & computer science
Function Machines: Parameters, Arguments and Return Values
Students trace short Python-style functions on paper, match key vocabulary, and write two small functions of their own.
Mathematics
Function Notation: What Does f(x) Mean?
Students evaluate functions written in f(x) notation, complete a function table, solve for an input, judge true/false statements, and apply a taxi-fare function.
Mathematics
Integers on the Number Line: Temperatures, Depths and Balances
Students order integers, find absolute value, and add and subtract integers in temperature, depth and money situations.
Science
Ionic, Polar or Nonpolar? Using Electronegativity to Classify Bonds
Students subtract electronegativity values to classify ten bonds as ionic, polar covalent or nonpolar covalent and count valence electrons in four molecules.
Mathematics
Limits on Paper: Tables, Patterns, Algebra
Students estimate limits from tables of values, compare left and right limits, and find limits by substitution and factoring.
Mathematics
Literal Equations: Solving Formulas for Any Variable
Students rearrange familiar formulas to isolate a chosen variable, apply them to real numbers, and match formulas to their rearranged forms.
Mathematics
Mean, Median, Mode and Range: Reading Time Survey
Students build a frequency table from survey data and find the mean, median, mode and range of two data sets.
Communications & media
News Values and the Upside-Down Pyramid
Students match news situations to the six news values, sort facts into the inverted pyramid, and write a short news story in pyramid order.
Technology & computer science
Pictures Made of Numbers: Pixels, Run-Length Codes and RGB Colors
Students turn binary rows into a pixel picture, shorten rows with run-length codes, read red-green-blue color values and calculate how much storage a small image needs.
