Presentation #4: Cubing Chain (10 cube chain or 1000 chain) The cubing chain is presented to the child in the same manner as the 100 chain with the exception that the labels are included from the beginning. The cube is brought to the mat and laid carefully on the top left corner of the mat. Bring the ten 100 squares to the mat and lay them out left to right along the top of the mat. The chain is then brought over carefully and laid out. This will require a series of mats or a strip that has been especially prepared for this work. Fold the chain into 10 squares and place a fixed square beside each folded square. Show the that the cube is made up of 10 squares. Count the number of squares laid out, and then count the number of squares in the cube. Carefully build the 100 squares into a (loose) cube. Compare this to the cube. ‘fixed’ Stretch the 1,000 chain out to its full length and replace the ten 100 squares at the end of each section of the chain. Count and label as before with the 100 chain. Note: When the 10 cube is laid out, you may also take the chain of 100 and move it along the 1000 chain to show how it is made out of ten 100 chains joined together. Work of the Teacher: Points of Emphasis: Careful handling of the material, how to remove and replace in the cabinet. Folding chain into squares. Language: Square, cube, numbers Beauty of the squaring and cubing materials. The Points of Interest: length of the chains. Counting high numbers. Work of the Child: Points of Consciousness: Visual perception of what a and a ‘square’ ‘cube’ are in numerical terms. You can count in number (skip counting) “chunks” Control of Number tags in order, the teacher. Variations: Place number tags on a separate mat. flipping activity, point to tickets randomly and ask child, much is this?” Turn over ticket to check. “How Repeat all tickets are right side up again.
