I have been asked how to use the Doman “red dot cards” to teach Math to a child. There are many ways you can do this, but if you want specific step-by-step instructions, then there are these are the methods that I am aware of:

- Doman’s Math Method – outlined below; and
- Shichida’s 65 Day Math Program
- BrillKids Little Math Program

Both programs are pretty similar. The fundamental difference is the number of repetitions. Doman’s method includes a lot more repetitions. You can find the step-by-step instructions for teaching Math following Doman’s method from Glenn Doman’s book “How to Teach Your Baby Math“, or you can follow the outline I have prepared here (I’ll cover the Shichida Math Method in another post):

Materials required: Set of 100 red dot cards (you can download the set I made, buy the Math Kit from Glenn Doman, or you can make your own).

#### BrillKids Little Math – Doman’s Math Method

If you have the BrillKids Little Math software, you can also download these “open and play” files for Doman’s Math Method.

**Teaching Quantity**

Day 1: Morning – Take the first ten dot cards: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10.

1. Shuffle and divide into two sets of five cards.

2. Flash the cards at the rate of one card per second and say the number as you flash the card.Afternoon – Repeat step one and two.

Evening – Repeat step one and two.

(Technically speaking, you don’t have to flash the cards in the morning, afternoon, and evening. There must be an interval of at least 15 minutes between each session).

Day 2: Repeat Day 1

Day 3: Repeat Day 1

Day 4: Repeat Day 1

Day 5: Repeat Day 1

Day 6: Remove cards representing 1 and 2. Add cards representing 11 and 12. Repeat step one and two from Day 1 once in the morning, afternoon, and evening.

Day 7: Remove 3 and 4. Add 13 and 14. Repeat step one and two from Day 1 once in the morning, afternoon, and evening.

Day 8: Remove 5 and 6. Add 15 and 16. Repeat step one and two from Day 1 once in the morning, afternoon, and evening.

Day 9: Remove 7 and 8. Add 17 and 18. Repeat step one and two from Day 1 once in the morning, afternoon, and evening.

Day 10: Remove 9 and 10. Add 19 and 20. Repeat step one and two from Day 1 once in the morning, afternoon, and evening.

**Introducing Addition**

By this stage, you child has learned quantities from 1 to 100, and seen 360 equations consisting of addition, subtraction, multiplication and division.

Now you can choose to show more complicated math equations, for example: 4+5+6+7=22, 15+6-2=19, 5×8/4=10. You can also teach your child about the quantity zero and show various equations relating to zero. You can show the different mathematical operations: +, -, x, /, =, <, >, ≤, and ≥. You can show sequences, for example: 1+1, 1+2, 1+3, etc. You can teach anything you want.

Thank you so much for the brief.It gives us new hope towards RBS,for the new moms like me.

hi dr…

Hope you are good. In ready to play doman cards section ..only till day 24 is available…whether remaining part is available somewhere else ?? sorry for the inconvenience

Hi Rahila – this page is still a work in progress with new days added every couple of days. You can begin now. I will be sure to keep ahead of your progress.

Thank you very much

Hi Shen-Li,

Thank you so much for this clear and detailed explanation!

I’m just wondering how you show multiplication and division equations? Do you just say “Four times three equals twelve”, while showing the appropriate cards, and the child somehow gets it? Or do you show them four cards with three dots each? How exactly does it work?

Thanks again!

My pleasure Aura. Yes, in the instructions from Doman, you would say “four (show four dots) times three (show three dots) equals twelve (show twelve dots). This may help your child know the answers to multiplication but I feel it is still important to teach with physical manipulatives later on why 4×3=12 by demonstrating 4 groups of 3 objects becomes 12. The latter will help reinforce the “why” and build a deeper understanding for later maths.

Regarding your other question – all ten cards are flashed three times a day. I don’t know why Doman advises us to divide the cards into two lots of five but all ten cards are shown in the same session. So it’s really three sessions of ten cards, just that the ten cards are shown five at a time.

Thank you!

Sorry, one more question: you say at the beginning to divide the 10 cards into 2 sets of 5, and then flash them three times a day. Does that mean flash all ten three times a day? Five in each session, so you’re doing six sessions, or all ten in each session?

How and when to introduce algebra? Please guide

Hi Neha – algebra is quite an abstract topic so it can be trickier for children to understand. There is a wonderful app called DragonBox which introduces algebra concepts to children in a fun way through game play. It is recommended for children from age 5. You can see it here – https://dragonbox.com/

Thank you so much for your reply. My kids are 2.5 year old. So which math concepts can be introduced at this age group and how? Please guide

Hi Neha,

At this age, you can play simple games that reinforce basic arithmetic concepts taught in Doman’s red dot card program – addition, subtraction, multiplication and division. You can supplement the learning using manipulatives to help young children understand it through a concrete demonstration. E.g. using counters, you can show that 4 items plus 5 items equals 9 items; 4 items multiplied by 5 times equals 20 items.

You can also demonstrate the concept of fractions – I can cut this cake in half; one slice is one eighth of the cake; when we share this portion, it is one sixteenth. You can also use manipulatives to reinforce fractions learning or things like LEGO blocks make great hands-on learning for math.

In the kitchen, you can teach concepts measuring – weight and cups – through cooking recipes. Making something they like to eat adds an aspect of fun to the learning.

You can teach your child the names of shapes – square, rectangle, triangle, hexagon, circle, etc. Look for objects that match these shapes – e.g. a stop sign is an octagon (it has 8 sides).

Teach patterns – arrange the blocks in alternating colours, e.g. red, blue, red, blue. When that’s easy, add another colour (or shape).

Compare sizes – can you order these toys from smallest to biggest?

Order – which one is the third one? Fifth one? 10th one? etc.

There are so many different games you can play that can incorporate math elements.
