## 12 yellow and 10 blue

Prepare in advance 12 yellow and 2 blue cubes

Make 2 groups of yellow and blue cubes. One group should consist of 12 yellow cubes. Another group should consist of 10 blue cubes. The cubes in the groups should be scattered in a random order, not put in a straight line or row. The two groups should be located away from each other to make them distinctive groups but not too far from each other so that the baby can see two groups in one location. Smile and say: Baby, which group do you think is larger and which one is smaller? Let’s make predictions! I think group 1 (place your hand above it) is larger. Now we can check it out. Let’s build two towers: one yellow (point to the yellow cubes), and one blue (point to the blue cubes). Start putting yellow cubes in one tower, counting: 1, 2, 3, 4, 5, … 12. Say: There are 12 (show 12: first show 10 fingers and then 2) cubes in the yellow tower. Now we will build another tower with blue next to the yellow one. Start putting the blue cubes, counting: 1, 2, 3, 4, 5…10. Say: There are 10 (show 10 fingers) cubes in the blue tower. Place your hand over the first tower. Say: here there are 12 cubes. Place your hand over the second tower. Say: and here there are 10 cubes. The yellow tower is higher than the blue one. The blue tower is shorter than the yellow one. That means that yellow cubes are more than blue ones. Let also put them in rows and see which row will be longer. Put all yellow cubes in one row counting. Put blue cubes in another row under the yellow one counting. Point to the first row and say: the yellow row of cubes is longer. It means yellow cubes are more. Point to the blue row and say: the blue row of cubes is shorter. It means the blue cubes are less.
