Number Hunt
Go hunting
Pick a number, say 2. Challenge your child to go on a treasure hunt to find as many ways as possible that 2 shows up around you. It may show up as the numeral 2 on a wall, sign, or building. It may show up as two of something, such as two chairs, two dishes, or two cups, as it does in this illustration.
If you like, you can make this into a contest by seeing who can find the most of whatever number you are looking for.
