My 3 1/2 year old made a number line yesterday and it turned out so cute! Simple and easy, but effective and CUTE! All we did was use small cheapy paper plates, I labeled them with 0-10, and then my son used Do-a-Dot paints to put the corresponding dots on the plates. Eventually we’ll go up to 30, but we’re taking it slow. Here are some visuals! Happy Homeschooling!!
