At an adventure camp, Emek and Luna organized supplies before the next expedition. Pixel counted the boxes as they placed them into storage. One area needed 5 groups of ten boxes and 7 single boxes, so they built the number 57. Another area needed 3 groups of ten boxes and 9 single boxes, making 39. By matching each number to the correct storage area, they kept the supplies organized and ready for the journey.
