Today students build a staircase with Cuisenaire Rods and extended the patterns they saw in order to find the number of white rods needed to build a staircase of a specific height. First, students were given the opportunity to explore and build with the rods. Students were then shown the value assigned to each of the rods. Next, students were challenged to build staircases out of the rods. Afterwards, we examined the staircases and discussed the number patterns. Students said this staircase was shrinking by 1s. Students said this staircase was shrinking by 3s starting at 30. Finally, students were given the challenging math task below. |
