2 variable linear simultaneous equations in k-3

I looking for help. I'm working with a 5 year old in the Stanford EPGY
program. She's progressed rapidly through K, 1, and the first half of 2nd
in EPGY. But simultaneous equations seem to be a big stumbling block. She
gets them but with difficulty and always by trial and error. Has anyone
thought about manipulatives appropriate for whole number, 2 variable,
linear, simultaneous equations?

I've thought about building a clear acrylic frame where various size
disposable measuring cups can either sit above a shelf or through a whole
in a shelf with only the thin rim supported by the shelf. Using pennies or
candies provides the discreteness and leaves open the use of liquids later
for fractional solutions.
