Graphing Google Slides Math Center. Find the most and/or least on each slide in three different ways: with pictures, numerals, and tally marks! Compare graphs containing two items, three items and even four items. Slides can be used separately to introduce and then, extend graphing concepts or altogether as an assessment piece. Cute, colourful and culturally diverse clipart is used. Perfect for whole group lessons on the interactive whiteboard, centre times, or Google Classroom.
