Mathematics
Angle Relationships: Find the Missing Measure
Students use complementary, supplementary, vertical, triangle and parallel-line angle facts to find missing angles and correct sample work.
Mathematics
Arithmetic Sequences and Linear Growth
Students find common differences, extend arithmetic sequences, use aₙ = a₁ + (n − 1)d, and model plant growth and savings with linear equations.
Science
Balancing Chemical Equations: Count, Adjust, Check
Students balance eight chemical equations by changing coefficients only, count atoms in a table, and judge sample balancing attempts.
Mathematics
Completing the Square: Perfect Squares and Vertex Form
Students find the missing term of perfect-square trinomials, solve three equations by completing the square, and rewrite a parabola in vertex form.
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.
Mathematics
Factoring Basics: GCF, Trinomials, and Zero Products
Students factor out the GCF, factor simple trinomials and differences of squares, solve quadratics with the zero-product rule, and find factoring errors.
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
Multi-Step Equations: Distribute, Combine, Solve
Students solve eight multi-step equations that need distributing, combining like terms, and moving variables, then find errors in sample work.
Mathematics
Order of Operations: PEMDAS Practice and Parentheses Puzzles
Students evaluate expressions with exponents and parentheses and place parentheses to make equations true.
Science
Photosynthesis and Cellular Respiration: Two Sides of One Cycle
Students compare photosynthesis and cellular respiration with an equation organizer, sort statements by process and count atoms to see that matter is conserved.
Mathematics
Sine and Cosine Graphs: Amplitude, Period, Midline
Students read amplitude, period and midline from sine and cosine equations, build a table of values, and write equations from descriptions.
