STEP 2 of the Rhythm Lab. Also in the series bundle. Self-checking rhythm practice for Grades 3-4: count the beats in 4/4 measures, find what is missing, and hear which notes fill the gap. 30 cards, 20 scored. THE MUSIC IDEA In 4/4 time the top 4 means 4 beats in every measure and the bottom 4 means a quarter note gets 1 beat. Bar lines split the music into measures; a double bar line ends it. HOW IT WORKS - 4 learn cards: measures and bar lines, count a measure, finish a measure, listen and fill. - Round 1: full, needs more, or too many beats? - Round 2: type how many beats are missing. - Round 3: pick the one note that finishes the measure. - Round 4: hear two measures. Every choice fills the 2-beat gap; only one matches the sound. - Reveal cards after every round. - 1 acorn = 1 beat; 20 acorns light up as you go. SELF-CHECKING, WITH HELP WHEN STUCK - Boom scores every answer. - Two tap-to-show hints per question. - A soft tick on every beat, stronger on beat 1 of each measure. ACCURACY Every answer is checked by our own software and by AI test solves from the cards and sounds alone, without the key. Not tested with a class. No process is perfect; if you spot an error, please tell us through the store's feedback. HOW IT WAS MADE Text written with AI assistance and fact-checked. All images and music notation are drawn in code; no AI image generators were used. All sounds are made in code. No AI voice. Needs sound. Plays in a browser; needs internet.
