My daughter, who is six years old, has been learning about numbers for awhile using both a natural and more structured approach to her learning. She is very curious about numbers and always eager to explore them. So I wanted to introduce her to the Montessori Number Rods. I love that Montessori uses concrete hands-on learning materials that make abstract concepts more clear which supports the learner to make progress, at their own pace, towards understanding these abstract concepts.
I originally looked at purchasing a set of number rods for my daughter to use instead, I came across this Easy DIY Montessori Number Rods and was inspired to make my own. So with the help of my husband, we made our own number rods. We adjusted the measurements (5cm long for each colour) to make our rods slightly shorter to fit our learning environment. I placed our number rods on a long tray and put it on our math shelves.
Montessori Primary Guide have a great step by step lesson plan for introducing number rods to learners if you would like to read about a more structured approach. For us, I waited for my daughter to choose this activity from our shelf before talking with her about the rods and exploring how we could use them together.
We first talked about the lengths of each rod and how some were shorter and others were longer. She wanted to order the rods from smallest to biggest before I encouraged her to count the coloured squares to check her work. This was followed by placing number tiles next to each rod to representing the rod’s value. Although I offered a lot of scaffolding the first time she chose this activity, she was able to repeat this activity again by herself independently.
I wanted to introduce my daughter to addition using the number rods. Again I waited for her to suggest the concept of addition which did not take very long for this to happen. We started by making 10. We laid the 10 rod out and matched two smaller rods (4 and 6) to equal to 10. We repeated this process a number of times adding different number rods together to equal 10. The same activity can be done to make 9’s, 8’s, 7’s, 6’s, 5’s, 4’s 3’s and 2’s.
Addition led to exploring subtraction with the number rods. Again we started with the 10 rod and selected a smaller rod to “take-away”. My daughter preferred to place the rod on top of the 10 rod so she could count how many we left over as well as being able to see which rod fit. This was a little tricky for her so we stopped it and went back to addition.
Last year we made a trip to our dentist and sadly, my son had to have a tooth removed as it was badly decayed. Since that visit, my children have been very focused on learning about their teeth and how to keep them healthy. They have had lots of questions about why we have teeth, why do teeth fall out, how come there are different size teeth, what happens when you break your adult teeth, what are braces? So here are some of the interest-led ways we have learned about our teeth over the last few months.
I put together a little basket of all the “teeth” related items we had. Our dentist was kind enough to give us teeth molds for my kids to explore and I found some of my old plates (yes, I used to wear braces), some baby teeth that had fallen out and my sons newly extract molar. I left these items on our learning shelf to encourage an interest and to provoke curiosity and further questions.
Keeping Our Teeth Clean
Our dentist had talked with our children about how to brush their teeth so each tooth is cleaned preventing plaque build up and decay. To help my children remember how to brush effectively I found these sequence of teeth brushing visual prompts that we hung up in front of our bathroom sink. In doing this, my children are reminded on how to brush ALL of these teeth and what sequence they could do it in.
As the interest in teeth continued to grow, I purchased a Science Time Dentistry Deluxe kit from Big W and the kit came with some fantastic hands-on resources, including this permanent teeth model. We used our teeth model to practice brushing teeth making sure we got all the teeth especially at the back. We also watched How To Bush Your Teeth on You Tube and looked at how to floss our teeth as well.
Types of Teeth
My son lost one of his deciduous (baby) teeth and this sparked a curiosity about the different types of teeth and why we have them. So we used the manual that came with our Dentistry Deluxe kit to read about the names of the different teeth, to look at their sizes and what their main jobs are. We looked at molars, premolars, canines and incisors and removed these teeth from our model to see their different shape.
I also downloaded these FREE teeth development nomenclature cards from The Pinay Homeschooler. Because we had already talked about the name of each tooth and what they do, I simply placed the cards in a basket on our learning shelf. This approach works well with my children as it gives them the opportunity to select the activity independently and when they are curious about it rather then me having to direct them.
Parts of Teeth
The dentist had talked about tooth decay with us and this was something that my son (9 years old) wanted to know more about. He started by looking at Tooth Decay on You Tube and searched through some of our human body books. He found a diagram of a tooth and constructed it with play dough noting each part of the tooth and how decay attacks the enamel.
Miss 5 took particular interest in tooth decay as well. She used our Tooth Model from Modern Teaching Aids and her understanding of tooth decay to draw a diagram of decay attaching a tooth. She easily explained to me how tooth decay works and what she needs to do to avoid getting holes in her teeth.
