The Khan Academy Kids app is really well balanced - a logic exercise followed by a book about dump trucks, a counting game followed by a singalong. It worked for my 4 year old. If you see some particular math/ science engagement I’ve found Magic School Bus (books / 90s show/ recent reboot )provides an excellent framing. The Singapore Math Series helped my daughter rocket a few years ahead of her classmates (your mileage may vary here).
