To begin the unit, students were all given different sizes of marshmallows. Have you seen how many different shapes and sizes there are of marshmallows now? We worked on ordering these marshmallows by length and comparing the marshmallows to a standard unit. CCSS.MATH.CONTENT.1.MD.A.1 We got really good at expressing our thoughts in "length" words. Words like longer, shorter, taller, wider, etc. became common vocabulary in our classroom. This helps to understand the idea of comparing length rather than size. Size words might be bigger, smaller, larger and so on.
Students practiced the rest of the week practicing their measuring skills with marshmallows. They first got the hang of things by measuring objects on measuring mats and then quickly moved to measuring mugs, hot chocolate packets, school supplies and more. We really had a fun week and learned so much with this unit. If you would like to check it out for yourself, you can find it here!
