I was wondering if this was essential for the learning process of five or six year olds.
Making maths enjoyable for young children would be the primary concern, but showing something meaningful (not necessarily to them) being done with maths by someone meaningful (to them)? It would work better if:
The kids require to see something that is relevant to their interests or needs being solved with maths by any old codger, as long as said codger can adequately manipulate algebra.
By the way, who is going to teach these children algebra? A fair number of teachers won't be up to the task. Reminds me of the learn to code buzz-phrase being passed around - first off you need to spend money and time on teaching teachers how to code.
EDIT: bloomin' asterisks.
