Online GeoGebra classes the first Saturday of each month. Next class is 01 April 2023, 9-11am CST/UTC-6. Buy tickets now via EventBrite.
Starting in January, Patreon subscribers at the $10 Narwhal and above tiers will receive physical rewards in the mail each month! Expect stickers, postcards, whatever fits in an envelope. I've been having a blast designing stickers lately and can't wait to share.
