How to make a dot board or card
D. Russell
Use cardboard (not plastic or foam type, because they don't look good) or cardboard to make various dots or cards with the provided patterns. Use bingo dabber or stickers to represent "dots" or dots on the plate. Try to arrange the points in various ways, as shown in the figure (if there are three points, make a row of three points on one plate and arrange the three points in a triangle on another plate. If possible, use 1- to represent the three-point arrangement of a number. When finished, you should have about 15 points or cards. These spots should not be easily wiped off or peeled off, because you will want to use these plates over and over again.
Depending on your child's age, you can use one or two plates at a time in the following activities. Every activity will make you lift a plate or two and ask questions. The goal is to let the children know the shape of the dots on the plate. When they lift it, they will recognize it as 5 or 9 relatively quickly. You want children to identify numbers by counting them one by one and then arranging them. Think about how you can identify the numbers on the dice. You don't count points, but you know that when you see a 4 and a 5, it's 9. This is what you want your children to learn.

Suggestions for use
Hold up a plate or two and ask what number it/they stand for, or how many points there are. Do this many times until the answer is almost automatic.
Use a dot board to represent the basic addition fact, and lift two boards to sum.
Teach 5 and 10 anchors with a point board. Hold up a board and say something greater than 5 or 10, and repeat it often until the child responds quickly.
Do multiplication with a dot board. No matter which fact you are studying, pick up a scoreboard and ask them to multiply it by 4. Or keep 4 and continue to show different chessboards until they learn how to multiply all the numbers by 4. Introduce a different fact every month. After knowing all the facts, lift two plates at random and multiply them by 2.
Use plates larger than 1 or smaller than 1 or larger than 2 or smaller than 2. Hold up a plate and say that this number is negative 2 or this number is positive 2.

in short
Pointboard or card is just another way to help students learn the conservation of numbers, basic addition facts, basic subtraction facts and multiplication. However, they do make learning interesting. If you are a teacher, you can ring the bell with a clapboard every day. Students can also play with some boards.
