Frog is brewing up another potion, but this time, the ingredients are a secret! Frog’s Secret Ingredient is a musical decoding activity that combines note reading and interval recognition to reveal a secret message.
This activity is great for students who can identify notes in the Middle C hand position!
Students start with a note on the staff, then follow the interval instructions to find the next note. Once they’ve figured out the interval, they write the letter name in the box and use it to decode Frog’s secret ingredient.
Want an extra challenge? Have your students draw the second note on each staff before writing the letter name.

If you missed last week’s Halloween printables, be sure to check out Frog’s Potions and Frog’s Potion Ingredients, too! Those two worksheets focus on recognizing harmonic intervals, so they’re a fun way to practice a different kind of interval reading.
Happy Halloween! ๐๐ธ

These are the same intervals students practice in Interval Jump! On the worksheet students follow each interval clue to the next note; in the app, Frog jumps the same distance from one log to the next while students quickly identify each interval on the staff.
The worksheet gives students a little more time to look and think, then the game lets them practice recognizing the same intervals a little faster.
Interval Jump is free to download, and the unison, 2nd, and 3rd are included in the free version. Interval Jump Pro adds the 4th through the 9th.
