Visual Discrimination plays a critical role in a child's ability to learn to recognize letters, numbers and other symbols. It is one of the important building blocks in learning to read.
If a child can not discriminate the letter "b" from the letter "h", he may read "bit" instead of "hit". Later on, this may be seen as a "learning disability" when it is really just underdeveloped visual discrimination skills.
In this game, each child is given the same set of blocks.
The "teacher" builds a structure with the blocks. The rest of the children replicate the structure.
We get a lot of practice because each child gets a chance to be the teacher.
Teacher: Every item in this hoop follows a rule. Each item is the same in some way. Can you tell me how all of these objects are the same?
The rule is, everything in this hoop must be.....
Student: Everything is red.
Teacher: Everything is red? (points to a bear) Is this red? (points to triangle) is this red?
Now we can say that the rule for this hoop is that everything inside this hoop must be red.
What about this hoop? What could be the rule for this hoop? Everything in this hoop must be....
Student: They're all different colors!
Teacher: They are all different colors. That's a way that they are different. Is there a way that they are all the same?
Student: They're red!
Teacher: Yes, some of them are red. Are all of them red? (points to red one) Is this one red? (points to another red) Is this one red? (points to a yellow) Is this one red? (points to a blue) Is this one red?
Are all of them red?
Teacher: Then that can't be our rule. Everything in this hoop is the same in some way. How are they all the same?
Student: They're bears.
Teacher: Are they ALL bears? (points to one) Is this a bear? (points to another) Is this a bear?
Our rule for this hoop can be that everything in this hoop must be a bear.
Teacher slides the two hoops so that they overlap.
Teacher (points to the yellow hoop): Everything in this hoop must be a...
Teacher (points to the red hoop): And everything in this hoop has to be...
Teacher: And here, in the center, it is part of the yellow hoop (teacher outlines yellow hoop with pointer finger). It is also part of the red hoop (teacher outlines red hoop). Since it is part of this hoop, everything in here has to be a bear. It is also part of this hoop (teacher outlines red hoop), which means that it also has to be....
Teacher: To belong in the center, it has to be a bear and it has to be...
Teacher: Can you find anything that belongs in the center? Something that is a bear and red?
The products used in this lesson are Attribute Blocks and Counting Bears.
I highly recommend both of these products for their versatility in math instruction.
