Here are 20 days of daily math warm ups. Each warm up includes 1 CGI (Cognitively Guided Instruction) word problem and appropriate math problems for the first trimester of first grade. For example, less than/greater than, base 10, addition and subtraction within 20, sides and corners of 2D shapes, and true/false equations. I use this packet as my daily math warm up. Please let me know what you think!
