- Use index cards with the numbers 0-9 and pipe cleaners. Have your child line up the cards in a row and put the number of pipe cleaners beneath each card. Make sure you have 45 pipe cleaners exactly. The child will be able to self-correct- if there are any pipe cleaners left, or he runs out, he will know there was an error. (The numbers 0-9 are all the numbers there are in our decimal system, if you think about it. Above 9, you move into the “tens” column with a “1” and a “0”.)
- Use little terra cotta pots, labeled with a sharpie with the numbers 0-9, and 45 glass beads.
- Print out a blank Hundred Chart, get a 10-sided die with the numbers 0-9 on it, and 100 buttons. Have your child roll the die and place the buttons on the chart (in an orderly progression, left to right, top to bottom) and continue until she’s filled up the chart. Make it a game and have two play at the same time; the one who fills the chart first wins.
- I’ve always loved these Grid Games. I laminate them and use a variety of counters.
- Create a table with 10 squares and give your child a mini stamp and stamp pad. Label each box of the table from 0-9 and have them stamp the amount in each box.
- My kids love this Ocean Race game. They roll a die and cross off one of the numbers that was rolled. The first number to be rolled ten times, wins.
- Here are some more counting ideas.
- Use the Montessori bead stair.
Once the child has learned to consistently count well, it’s time to introduce the teen numbers, and the decimal system. The Montessori bead materials are wonderfully designed and beautiful to look at. They provide everything needed to learn the decimal system, skip counting, squares, and multiplication tables in a concrete, hands-on way. You can make the bead materials yourself with pony beads and pipe cleaners. Make sure, however, that each number is a different color, 1-9. You can see a post about making the materials with wire and beads, and also see which colors are for which bead number here at Homemade Montessori.
Lessons are designed to identify each step in learning about numbers in a very simple and non-frilly way. You can see a video example of a teen bead lesson here.
Introducing the decimal system is just a small step further, and a Montessori child who has already been familiar with numbers 0-9 and one-to-one correspondence, is ready to learn that when you have ten of something, you trade the ones in for a ten. Then when you have ten tens, you trade them in for one hundred, and trade ten hundreds in for one thousand. The bead materials make this very clear in the way they are created since ten ones wired together is a ten, ten tens wired together is a hundred, etc. Laid out in this fashion, and with the concrete, hands-on materials, the decimal system is easy for even a 4 or 5 year old to grasp.
Here is a video example of the Montessori Bank Game. We have some of these materials (ones, tens, hundreds, thousands) but not the exact Montessori materials. These are a very important addition to your homeschool, so I would suggest having these in your home. There’s really nothing like being able to manipulate these tangible examples of an abstract concept such as our decimal system.
Once you have worked with your child and he understands the ones, tens, hundreds, and thousands and how they function together to create larger numbers, the next step is addition, and then subtraction.
Here are some other math activities:
- We have this hundred board which you can make yourself using any number of different materials. It is wonderful for skip counting, ordering numbers, etc.
- Pattern blocks: make hexagons using triangles, rhombuses, and trapezoids, use these templates, printed and laminated.
- Fraction insets for exploring parts of a whole. You can also find plastic ones cheaper here.
- Number rods for number comparison and adding.
- I love the book, “Games for Math” by Peggy Kaye. I find that the games I play with my children go a long way in reinforcing what we are exploring in our Montessori time. There are many great games for working with the decimal system, for example.
Monday we’ll look at the Language materials and learn about how to use them.
If you’re not going to the HOTM Online Conference, you should be!
I’m giving away one ticket to the conference to a random reader and commenter today. To enter, simply leave a comment on this post telling me what interests you most about the Montessori Method. I will draw a name at random on Sunday, February 13th before I go nighty night.
