ALEX Lesson Plans Subject: Mathematics (1 - 2) Title: Using Sign Language to Write Four-Digit Numbers in Words Description: In my experience, children love to learn and experiment with sign language. In this lesson, children will learn numbers 1-100 in sign language and will use that knowledge to sign four digit numbers to be written in words. This lesson plan was created by exemplary Alabama Math Teachers through the AMSTI project.Subject: Mathematics (1 - 2) Title: Souper Scooper Description: This hands-on, inquiry based lesson is an extension of the AMSTI Science Module, Solids and Liquids. Students use nonstandard units to measure beans in a soup mix. Students predict how many beans will be in a scoop. Students group beans by ones, tens and hundreds and complete a chart of their work. This lesson plan was created by exemplary Alabama Math Teachers through the AMSTI project.

The fish cut-out, with its mouth open, represents the greater than or less than symbol; the clam cut-out represents the equal to symbol. Using fish lips as a transition point, children will apply their understanding of greater, less, and equal to the standard symbols as the teacher introduces symbolic notation at an developmentally appropriate level.Thinkfinity Partner: IlluminationsGrade Span: K,PreK,1,2
