I came across this project at Deep Sparkle and decided to try this with Mavi.  I love how simple the project is and it uses basic colour combinations.  Since the project involves the colorwheel, Mavi and I revisited our basic art lessons about colours a few years ago. We talked about the primary and the secondary colours and how the are organised in a wheel type figure so we can easily remember the colour combinations.

Mavi worked on the red, orange, green and yellow combinations, while I painted a blue-violet flower combination.  And here’s how they looked like after we added  black and white paint details.

The flowers turned out really good and the colours were vibrant! You can see these hanging in Mavi’s room as of the moment.

Our dynamic addition starts with a brief discussion of what makes a 10 using a unit (1’s), 100 using 10’s and a 1000 using 100’s.  This is a visual presentation of smaller units that we can group together to form a bigger units.  From here, I told Mavi that whenever he encounters this when he plays Stamp Game, all he needed to do was to “substitute” the group with a bigger value.

The concept of dynamic addition in Montessori is the same whether you use golden beads, stamp game or bead frame.  Here’s how we do it:

• [Top left photo] Mavi would take out a strip of paper with a written equation and copies it in our booklet.  [Top left photo]
• [Top right photo] He would layout all the stamps according to the equation.  Then perform the addition by combining the two sets. See our Static Addition for this.
• [Lower left photo]  Count the stamps starting from the unit’s place value. He counted 13 units, grouped the 10 units (green) and replaced it with a 10 (blue).  As you can see, he was confused at first he put the 10 (blue) in the units area.  This I emphasized that he has to place it on the correct area in the place value mat.
• [Top right photo]  He recorded the sum after he worked on the tens and hundreds, applying the same concept of regrouping.

Note:  Mavi has memorized a lot of number pair in addition.  Most of the time he doesn’t use the stamps or beads, he automatically do the addition work.  Sometimes he would start on the thousands going down to the units. I have to explain that he always need to start from the smallest unit.  This is because he will produce an incorrect sum once the equation is dynamic.  That is the number changes (addends) because of the regrouping.  And he understood this somehow when finished a few equation strips.

Well, that’s all for dynamic addition for now.  This is just an introductory to my 6 years old.  We’ll practice more of this next year.

Here’s our homemade math learning material for skip counting.  You can avail a FREE copy by clicking on the image below.  We’ll use this next week so keep visiting my site if you want to see how we use it at home. Enjoy!

I wonder how you teach kids to skip count?  When I was younger this was one of the thing that I despise the most. Why? Because basically they just want us to memorise it.  With the available resources now, I want my boys to love skip counting…. as I always tell Mavi, you will use this technique all the time for the rest of your life :)

We had a few practice on this but I never had a the chance to come up with a serious unit or lesson for this.  Now he’s a bit older to understand and appreciate, I decided to come up with sheets to get him into the skip counting thingy.

First I created the hundred sheets, and discuss the concept about skip counting (by 2’s, 5’s and 10’s).  I cross-out the count in our sheets and made him mark it using our Do-a-Dot markers.

“Look Mom! It has a pattern!”

Now using these visuals, we put it into action using our decanomial beads and hundred board number tiles (both Montessori Math materials from Absorbent Minds UK).

Here we have the counting by 5’s.

And I compared it to the counting by 10’s.

And his least favourite skip counting is by 2’s (because it takes a long time to read 10, he said LOL).

Now well be practicing this for the entire week.  I’m coming up with materials so we can use the concept using non-Montessori materials.  I’ll be sharing it with you so watch out for it.
