## Pick-a-Path

Help Okta reach the target by choosing a path from the top of the maze to the bottom. Seven levels with seven puzzles will test your skills with powers of ten, negative numbers, fractions, decimals, and more. How many starfish can you earn?

An instructional guide — with details about the math concepts in the app, tips for using Pick-a-Path in the classroom, additional instructional activities, and other useful information — in addition to lessons and other supplemental resources for teaching with Pick-a-Path on the Illuminations website.

## Deep Sea Duel

Okta challenges you to a duel! Collect cards with a specified sum, and you win! But you better do it before Okta does! Choose how many cards (9 or 16), what types of numbers (whole numbers or decimals), and Okta’s level of strategy (easy to hard).

Prefer playing on a computer? Come to Illuminations where we have a web-version of Deep Sea Duel. Would you like some help refining your strategy?

## Okta's Rescue

Oh, no! Okta and his friends need help. Help rescue them by transporting them to a safe ocean. How fast can you transport the Oktas? Use your counting skills to save as many as you can before the timer runs out.

## Equivalent Fractions

Create equivalent fractions by dividing and shading squares or circles, and match each fraction to its location on the number line. Check your work, and use the table feature to capture results and look for patterns. Got a particular value for which you’d like to make equivalent fractions? Use “Build Your Own” mode.

Illuminations has a web-version of Equivalent Fractions, too!
