Deductive proof and geometric reasoning MATH · 10TH GRADE Name Date TAKE-HOME PRACTICE Math · 10th Grade 30 minutes WHAT THIS BUILDS Writes a valid proof where every step has a justification, and spots an invalid step in someone else's. 1 THE TWO-MINUTE CHECK ASK Give a two-column proof with one wrong justification. "Find the invalid step." A SOLID ANSWER Finds it and explains why that reason doesn't hold. Not yet Getting there Solid 2 JUSTIFY EVERY LINE You need: Paper, A geometry problem Write the given and the goal at the top and bottom before anything else. Work backwards from the goal: what would be enough to prove it? Write each step with its reason, and refuse any step whose reason is "it looks like it". Have them explain the proof aloud to you — gaps become audible immediately. Then find a flawed proof and identify exactly where it breaks. SAY THIS WHEN IT STALLS "It looks true isn't a reason. What theorem lets you write that line?" Fill in the missing reasons in a given proof. Prove a statement two different ways, and prove one false statement is false with a counterexample.

Triangle congruence and similarity MATH · 10TH GRADE Name Date TAKE-HOME PRACTICE Math · 10th Grade 30 minutes WHAT THIS BUILDS Applies the congruence and similarity criteria correctly and knows why SSA fails. 1 THE TWO-MINUTE CHECK ASK "Which criteria prove congruence? Why isn't SSA one of them?" A SOLID ANSWER SSS, SAS, ASA, AAS, HL — and can describe or draw the SSA ambiguity. Not yet Getting there Solid 2 BUILD THE AMBIGUOUS CASE You need: Straws or strips of card, A protractor, Paper Build triangles from given measurements and see which sets force a unique triangle. Try SSA and physically construct two different triangles from the same data. That construction is the reason the criterion doesn't exist — no memorisation needed. Use similarity to find a real height by shadow or by a mirror on the ground. Write one proof using each criterion. SAY THIS WHEN IT STALLS "Build it with the straws. Can you make two different triangles from that data? Then it can't be a rule." Identify which criterion applies to given diagrams. Proofs requiring two triangles and an intermediate result.

Right-triangle trigonometry MATH · 10TH GRADE Name Date TAKE-HOME PRACTICE Math · 10th Grade 35 minutes WHAT THIS BUILDS Uses sine, cosine and tangent to find sides and angles, and sets up problems from a described situation. 1 THE TWO-MINUTE CHECK ASK "A 20 m ladder at 70° to the ground — how high does it reach? Then: what angle makes it reach 15 m?" A SOLID ANSWER About 18.8 m, and about 48.6°, with the correct ratio and inverse chosen. Not yet Getting there Solid 2 MEASURE SOMETHING YOU CAN'T REACH You need: A protractor and straw as a clinometer, A tape measure, A calculator Build a simple clinometer from a protractor, a straw and a weighted string. Measure the angle to the top of a tree or building, and the distance to its base. Calculate the height with tangent, adding your own eye height. Check with a second measurement from a different distance — the answers should agree. Label which sides were opposite, adjacent and hypotenuse in each setup. SAY THIS WHEN IT STALLS "Label the three sides relative to the angle first. Then the ratio picks itself." Given diagrams, choose the right ratio and solve. Two-stage problems and angles of elevation and depression combined.

Circle theorems and arc relationships MATH · 10TH GRADE Name Date TAKE-HOME PRACTICE Math · 10th Grade 30 minutes WHAT THIS BUILDS Applies the circle theorems and explains which one justifies each step. 1 THE TWO-MINUTE CHECK ASK Give a circle diagram with a central and an inscribed angle on the same arc. "Find the missing angle and name the theorem." A SOLID ANSWER Correct value and the theorem named. Not yet Getting there Solid 2 ONE DIAGRAM, ALL THE THEOREMS You need: Compass, Protractor, Paper Draw one large circle and add a chord, a tangent, a central angle and an inscribed angle. Measure everything and look for the relationships before being told them. Write each theorem next to the part of the diagram that shows it. Then solve problems, naming the theorem for every step. Make a one-page reference sheet with a small diagram for each theorem. SAY THIS WHEN IT STALLS "Which configuration is that? Find the shape you recognise inside the mess of lines." One theorem at a time with clean diagrams. Multi-step problems needing three theorems, plus a proof of one of them.

Coordinate geometry MATH · 10TH GRADE Name Date TAKE-HOME PRACTICE Math · 10th Grade 30 minutes WHAT THIS BUILDS Uses distance, midpoint and slope to prove geometric properties algebraically. 1 THE TWO-MINUTE CHECK ASK "Given four points, prove the quadrilateral is a parallelogram." A SOLID ANSWER Uses slopes for parallel pairs, or midpoints of diagonals, and states the conclusion properly. Not yet Getting there Solid 2 PROVE THE SHAPE You need: Graph paper, Paper Plot four points and guess the shape. List what would have to be true for that shape: which sides parallel, which equal, which angles. Calculate the slopes and distances needed and check each condition. Write the conclusion as a proper argument, not just a set of calculations. Then try to prove it's something stronger — a rhombus, a rectangle — and see if it holds. SAY THIS WHEN IT STALLS "What would have to be true for it to be that shape? List the conditions, then test each one." Verify a given shape's properties with the formulas. Prove three collinear points, or find an unknown coordinate that makes a property true.

Surface area, volume and how they scale MATH · 10TH GRADE Name Date TAKE-HOME PRACTICE Math · 10th Grade 30 minutes WHAT THIS BUILDS Computes surface area and volume of composite solids and applies the square-cube relationship. 1 THE TWO-MINUTE CHECK ASK "Double every dimension of a solid. What happens to surface area and to volume?" A SOLID ANSWER ×4 and ×8, with the reason. Not yet Getting there Solid 2 SQUARE-CUBE IN THE KITCHEN You need: Sugar cubes, Water, A timer, Ice Dissolve one whole sugar cube and one crushed cube in identical water and time both. Explain the difference purely by surface area to volume ratio. Calculate the ratio for a 1 cm cube and a 2 cm cube. Apply it: why small animals lose heat faster, why cells stay small. Compute the volume and surface area of a composite solid from measurements at home. SAY THIS WHEN IT STALLS "Volume went up eight times but surface only four. What does that do to how fast it cools?" Compare two cube sizes numerically. Explain why an insect scaled to human size could not function, using the ratio.

Probability, permutations and combinations MATH · 10TH GRADE Name Date TAKE-HOME PRACTICE Math · 10th Grade 30 minutes WHAT THIS BUILDS Counts outcomes correctly and calculates conditional probability without falling for the classic traps. 1 THE TWO-MINUTE CHECK ASK "How many ways to pick 3 from 8 if order doesn't matter?" Then a conditional test-accuracy problem. A SOLID ANSWER 56, and awareness that a positive test doesn't mean the same as the test's accuracy figure. Not yet Getting there Solid 2 THE TEST ACCURACY PROBLEM You need: Paper, A calculator Set up a rare condition — 1 in 1,000 — and a test that's 99% accurate. Work with 100,000 imaginary people rather than percentages. Natural frequencies make it obvious. Build the table of true positives, false positives, and totals. Calculate the chance a positive result actually means the condition. It's shockingly low. Discuss why this matters for real screening decisions. SAY THIS WHEN IT STALLS "Don't use percentages. Take a hundred thousand people and count them — the answer becomes obvious." Counting problems with the formulas only. Bayes' theorem written formally after doing it with frequencies.

Keeping Algebra I sharp MATH · 10TH GRADE Name Date TAKE-HOME PRACTICE Math · 10th Grade 10 minutes weekly WHAT THIS BUILDS Retains fluency in equations, factoring, quadratics and functions while doing a year of geometry. 1 THE TWO-MINUTE CHECK ASK Set five Algebra I problems cold, with no warning or revision. A SOLID ANSWER Four of five, at speed, without needing to look anything up. Not yet Getting there Solid 2 WEEKLY ALGEBRA TEN You need: Old Algebra I problems, A timer Ten mixed problems from last year, once a week, timed. Rotate the topics: equations, factoring, quadratics, functions, exponents. Keep an error log and rework anything missed twice. Track the time as well as the score — speed is what fades first. Do a full Algebra I review two weeks before the year ends. SAY THIS WHEN IT STALLS "Ten minutes a week now, or three weeks of relearning it in September. Your choice." Five problems, untimed. Mix in Algebra II preview topics — rational expressions, systems of three equations.
