# MAA AMC Curriculum Inspirations

I believe in good and deep math, and good math appears in all sorts of places. Here are some essays and videos showing how to take some math from the competition world and bring it to the classroom in a way that a) is relevant and connected to the curriculum, and b) revels in deep, joyous, mulling and flailing, and reflection, and intellectual play and extension, and insight, and grand mathematical delight!

Big plans are afoot for this ever-growing contebt! STAY TUNED!
