Intro to Metric Conversions – 5th Grade Math

Order the metric prefixes (kilo, hecto, deca, unit, deci, centi, milli) using the mnemonic 'King Hector Doesn't Usually Drink Chocolate Milk'

Use a staircase model to convert between metric units of length, mass, and capacity

Recognize that moving down the staircase multiplies by 10 (shifts the decimal right) and moving up divides by 10 (shifts the decimal left) per level

Convert metric measurements involving whole numbers, fractions, and decimals (e.g., 50 centigrams to 0.5 grams, 200 meters to 0.2 kilometers)

Convert between liters and cubic centimeters using the relationship 1 liter = 1000 cubic centimeters

Have students copy the staircase and mnemonic onto their own paper early in the lesson, since the slides return to referencing 'the staircase' throughout later problems

Pause after each 'What pattern do you see?' slide (slides 44 and 48) to let students propose the decimal-shift rule themselves before the next slide reveals it

Use the multi-level conversions (e.g., 200 meters to kilometers, moving three levels) as a checkpoint for students who have mastered single-level conversions

Assign the two-question exit ticket individually to check whether students can apply the decimal-shift pattern without the staircase model visible

Metric unit ordering — students sequence the metric prefixes from kilo to milli using a staircase model and mnemonic.

Unit conversion — students convert measurements of length, mass, and capacity between metric units, including whole-number, fractional, and decimal results.

Pattern recognition — students discover and apply the rule that each staircase step multiplies or divides by 10, shifting the decimal point one place.

Multi-step conversion — students apply the decimal-shift pattern across multiple staircase levels (e.g., meters to kilometers) rather than a single step.
