Here is a video to actively get them counting to 10 in sequence, which can be used as a starter activity before they get painting. https://www.youtube.com/watch?v=uGL7xYEVeaY
Touch counting- Get the child to do as many fingerprints as they want on the page and you count them. Point to each print and give it a number. Then you do it for you child. To extend the learning your child could then write a number next to each fingerprint.
You can also write numbers on a page and get your child to do the correct amount of fingerprints next to the number using finger paint.
Adding single digit numbers- Give you child a number sentence e.g 4 + 6 =. They then have to do the correct amount of fingerprints under each number and finally count all the fingerprints together to gain the answer. We use this method in schools however, we normal use dots, so this way is much more fun!
Number bonds to 10- Use the finger paint to cover each of your child's hands. Then carefully cut round them. You stick the palms to an A4 sheet of paper making sure not to stick the fingers. Then you make a fold at the end of each finger. Write the sums for the number bonds to 10 with a missing number in the middle e.g 1 + __ = 10. They then use their hands to support them find the answer by putting one finger down and seeing how many are left to fill in the missing number.
Here is another video to warm up their minds and keep them active before starting their number bonds activity.
Odd and even numbers- Paint your childs finger tips using finger paints ONLY USE 2 colours. Start with the first finger and paint it a colour of their choice and paint every other finger that colour. Then use your second colour to paint the other alternate fingers. Then print the fingers onto paper and write a number above each finger. You can then explain how one colour represents odd numbers and the other colour represents even numbers.
Pattern- Repeating patterns can be fun to create. Use the finger paints to design a repeating pattern. Challenge children by introducing numbers!
Here is another fun video to introduce pattern to your child.
