Happy Halloween! Use ADDITION to uncover the hidden letters, and spell the Halloween-related words.
Each letter is hidden inside a set of boxes, and each box has a math problem. Do the math problems, select all the correct boxes (just like BINGO), and see the hidden letter.
Finish all the letters to reveal the secret Halloween Vocabulary Words! And listen to the spooky music...
Great homework practice for young & curious students, and a nice way for grown-ups to keep minds sharp. Screen time well spent.
Designed for ages 3 to 103! See the YouTube demo on our website.
