Below are two sets of value label cards to be used with the set of A-blocks in various exercises. Each card has a value on it. The first set has the full value written out and the second set has the abbreviations. Use whichever set you prefer to work with. There is a negative value card for each positive value card. By negative, I am referring to the complement of a set. For instance, there is a subset of BLUE (B) A-blocks. There are six elements in this subset The negative value card would be NOT BLUE $\left(\mathbf{B}^{\mathrm{c}}\right)$ and this represents the set of all A-blocks that are not blue. There are 18 elements in that subset. LARGE and SMALL are complements of each other so there aren't separate cards for their negative values. There are some extra cards left blank so that you can fill in some creative labels like $\mathbf{B} \cap \mathbf{T}$, $\mathbf{B} \cup \mathbf{T}$ or some other combinations needed for certain exercises. These cards need to be cut out and saved along with your A-blocks. Preferably, this is on cardstock paper or laminated. If not and these labels are too flimsy, you can make some labels on index cards so they are sturdier.
