A complete 14-day Grade 5 unit covering all of CCSS 5.G — the coordinate plane (plotting, reading, distances, real-world graphing) and shape classification (triangles, quadrilaterals, family-tree hierarchy). This is the unit where students develop the foundational geometry skills they'll carry into middle school. Built by a classroom teacher who knows that the "every square is a rectangle" concept is one of the biggest logical leaps Grade 5 students make, and that the coordinate plane is the gat

A complete 14-day Grade 5 fractions unit covering all of CCSS 5.NF. Built by a classroom teacher who needed something that actually works on a Monday morning — no prep, no patching together, no fluff. Twelve fully-scripted lessons take students from adding unlike denominators all the way to dividing whole numbers by unit fractions, with a real-world performance task at the end. Every lesson follows the same 10-slide structure students recognize from Day 1: Title → Learning Target → Hook → Direct

A complete 14-day Grade 5 unit covering all of CCSS 5.OA — the order of operations (PEMDAS), nested grouping symbols, writing and interpreting expressions, generating and comparing number patterns, and graphing ordered pairs on the coordinate plane. This is the bridge from arithmetic to algebra. Built by a classroom teacher who knows that students need to MASTER PEMDAS before middle school, and that expressions and patterns set the foundation for everything that follows. From "3 + 4 × 5" to grap

A complete 14-day Grade 4 unit covering all of CCSS 4.MD — customary and metric measurement conversions, area and perimeter formulas, angles and protractor measurement, and line plots with fractional data. Built by a classroom teacher who knows that measurement is where math meets real life. From converting feet to inches, to finding the area of a treehouse floor, to measuring angles with a protractor — every concept is built with clear language, real-world scenarios, and visual support Grade 4

A complete 14-day Grade 4 multi-digit operations unit covering all of CCSS 4.NBT. Built by a classroom teacher who knows that 4.NBT is the year students either CLICK with multi-digit math — or hit a wall that follows them to fifth grade. This is the comprehensive 4.NBT unit. From reading numbers in the millions, to the standard algorithms for all four operations, to long division with remainders, every concept is built with clear language, step-by-step instruction, and visual support Grade 4 stu

A complete 14-day Grade 4 unit covering all of CCSS 4.OA — multiplicative comparisons, factors and multiples, primes, patterns, and the bridge from arithmetic to algebra. Built by a classroom teacher who knows that 4.OA is where students start to think mathematically, not just compute. This is the comprehensive 4.OA unit. From recognizing comparisons in word problems, to finding factor pairs of any number, to identifying patterns and solving two-step equations, every concept is built with clear

A complete 14-day Grade 3 unit covering all of CCSS 3.MD — telling time to the nearest minute, elapsed time, liquid volume, mass, picture/bar graphs, line plots, area, and perimeter. This is the unit where students master the practical measurement skills they'll use for life. Built by a classroom teacher who knows that 3rd-graders need careful scaffolding through telling time on analog clocks (the trickiest 3.MD concept!), and that the jump from counting unit squares to using A = l × w is a defi

A complete 14-day Grade 3 unit covering all of CCSS 3.NBT — place value to the thousands, rounding to the nearest 10 and 100, multi-digit addition and subtraction within 1000 (with regrouping and borrowing), and multiplying one-digit numbers by multiples of 10. This is the foundation that every Grade 3+ math depends on. Built by a classroom teacher who knows that place value confusion is at the root of most computation errors, and that students need to MASTER three-digit operations before moving

A complete 14-day Grade 3 multiplication and division unit covering all of CCSS 3.OA. Built by a classroom teacher who knows that this is the biggest math unit of the year — and the foundation for every operation a student will see for the rest of elementary school. This is THE introduction-to-multiplication unit. No prior knowledge required. Every concept is built from scratch with equal groups, arrays, number lines, and clear language third-graders can actually follow. Twelve fully-scripted le

The school Halloween party candy fund — $240 collected over two weeks from eight classrooms — has vanished from the locked supply closet. Whoever took it did not guess the amount. They calculated it: the exact number of candy bags the fund could purchase at bulk price, the exact cost per bag, the exact total. Every piece of working found at the scene shows precise multiplication and division. No estimation. No rounding. Someone who uses these skills every single day did this deliberately. The Ma

The classroom counting jar — 48 pieces of Halloween candy collected over two weeks by the whole class — has been emptied overnight. Whoever took it did not grab blindly. They added and subtracted carefully to take exactly the right amount. The addition sums on the evidence tally are not random. The subtraction working connects directly to the missing total. Someone who adds and subtracts fluently did this — and does it automatically, without effort. The Math Whodunnit: The Missing Candy Jar is C

The donation amount labels on the winter gift drive charity table have been mixed up. Every label showing tens and ones has been swapped with a different number — and each swap was chosen deliberately to look almost correct. Whoever rearranged them understood place value well enough to make every change plausible to a quick glance. They know what a tens digit means. They know how skip counting produces a sequence. They know expanded form well enough to reverse it convincingly. Five suspects. Fiv

The winter charity collection jar — holding three-quarters of the school's fundraising goal after four weeks of donations — has been tampered with. The fraction records have been deliberately altered to hide how much was taken. Equivalent fractions were swapped to redirect funds across categories. Comparison signs between donation amounts were reversed. Addition totals were adjusted by exactly the amounts needed to avoid triggering an audit. Whoever did this understands fractions precisely. The

The Grade 2 class survey — 78 students voted for their favourite school lunch over three weeks — has been altered. The chart on the display board now shows that pasta is unpopular and pizza is the runaway favourite. But the students remember voting very differently. The school principal is using the chart results to make a budget decision this Friday. Whoever changed the numbers understood exactly how tally charts, bar graphs, line plots, arrays, and even-and-odd groupings work. Every number was

The geometry display in the main corridor has been rearranged. Shape labels have been moved to the wrong shapes — each swap chosen to be as plausible as possible to a young student. The measurement poster shows every value shifted by exactly 2 centimetres. The clock display has the hour and minute hands drawn in reverse for each time shown. Grade 1 students copied the display into their homework books last Tuesday and got every answer wrong. Whoever rearranged the display understood shapes, meas

The classroom number wall was rearranged overnight. The tens and ones labels are on the wrong shelves. The skip-counting posters show incorrect sequences — correct for the first two terms, then deliberately wrong from the third. The expanded form display is reversed. Sixty-two Grade 1 and Grade 2 students use this wall every day, and their homework results confirm they copied down incorrect information. Whoever did this understood place value well enough to make every change look almost right. F
