Allow students to measure staircase and platforms using non-standard units of measure. Examples- book lengths, elbow to tip of finger etc. Share measurements with the class. Instead of toothpicks, teacher may use larger magnets for easier visual. Students will construct staircases using toothpicks, glue and constructions paper.
Students share and discuss different constructions.
Students break into groups of 3-5 students. Using measurement skills and techniques, they will measure staircases and record in notebooks. They will use both sums of treads and risers as well as technique shown in video. They will share results with class. Discuss aspects of measurement with construction.
