This math flipchart for Promethean Board and Activ studio teaches students to demonstrate one half, to identify shapes divided in half, and to differentiate between shapes divided in half and shapes not divided in half. This flipchart is aligned with 9.2 Houghton Mifflin Math - 1st grade. The lesson opens with a word problem in which students must identify the number of faces on solid shapes. Next, is a quick review (test prep) and lesson quiz (pre-test) derived from the text. Next is a title page introducing the lesson and then a page stating the lesson's objectives. The lesson then introduces vocabulary term(s): half, along with the definition and visuals. The first activity displays a math story with halves. As the teacher reads this story, halves pop up in the text, in which students must identify the correct picture which the story describes. The next activity displays several shapes and students take turns circling the shapes that show two halves. Next, the students must shade in half of each shape given - one suggestion: allow students to do this in partners on paper, then check whole group on the Promethean Board. Then, the students are given another set of shapes that they may draw a line to demonstrate half. The next page allows for review and closure. Last is a math journal prompt that incorporates drawing.
