READ OUT LOUD. Choose which marked text you prefer to practice with - macrons in verse form, or macrons in prose order, or accent marks in prose order, or focusing on the iambic meter. You will find materials for all of these options below. :-)
VERSE MACRONS. Here is the verse text with macrons:
Iactīs in undās rētibus, magnī quidem
Captī sunt Piscēs; at minūtī sē īlicet
Extrīcāvēre, facile permeantibus
Corpusculīs fenestrās līneae domūs.
Fortūna rārō summīs iniiciēns manum
Fallitur: in īmōs manca saepius ruit.
PROSE MACRONS. Here is the same text with macrons written out in prose word order:
Rētibus in undās iactīs, magnī quidem Piscēs captī sunt; at minūtī sē īlicet extrīcāvēre, corpusculīs līneae domūs fenestrās facile permeantibus. Fortūna rārō fallitur, summīs manum iniiciēns; saepius manca ruit in īmōs.
STRESS (ACCENT) MARKS. Here is the prose text with accents, plus some color-coding for the words of three or more syllables (blue: penultimate stress; red: antepenultimate stress):
Rétibus in undas iactis, magni quidem Pisces capti sunt; at minúti se ílicet extricavére, corpúsculis líneae domus fenéstras fácile permeántibus. Fortúna raro fállitur, summis manum iniíciens; saépius manca ruit in imos.
IAMBIC METER. Here is the verse text with some color coding to assist in the iambic meter. The disyllabic elements (iambs/spondees) are not marked, but the trisyllabic elements are color-coded: dactyls are red, anapests are purple, and tribrachs are green (as is any proceleusmaticus, although that is a rare creature); for more information, here are some Notes on Iambic Meter.
Iactīs· in un·dās rē·tibus,· magnī· quidem

Fortū·na rā·rō sum·mīs in·iiciēns· manum
Fallitur:· in ī·mōs man·ca sae·pius· ruit.

What follows is an unmarked version of the prose rendering to faciliate word searches:
Retibus in undas iactis, magni quidem Pisces capti sunt; at minuti se ilicet extricavere, corpusculis lineae domus fenestras facile permeantibus. Fortuna raro fallitur, summis manum iniiciens; saepius manca ruit in imos.
