What to do
Give them couple of plain white papers and crayons. Let them keep the paper over different materials and color on them. They will be super excited to see that there are soo many different textures around them. You could ask them if they are rough , smooth etc. You will be surprised what they say to you:) My 3 yr old son said..."Look momy I made indentations on the paper!" Enjoy yourself with your kids this summer:) After that you can make a little booklet and decorate with colored paper.
