当孩子们学会计数时,它通常采取死记硬背或记忆计数的形式。为了帮助年轻学习者了解数量和数量,这套自制的点盘或点卡将是非常宝贵的,并且可以反复使用以帮助各种数字概念。根据孩子的年龄,您可以一次使用一个或两个盘子进行以下活动。每项活动都会让您举起一两个盘子并提出问题。目标是让孩子们识别盘子上点的形状,当他们举起时,他们会认识到它是相对较快的五或九。您希望孩子们通过一对一计数点,并通过点排列识别数字。想想你如何认识骰子上的数字,你不计算点数,但你知道当你看到4和5它是9时。这就是你希望你的孩子学习的东西。使用纸板(不是塑料或聚苯乙烯泡沫塑料类型,因为它们似乎不能正常工作)或硬质卡片纸使用提供的图案来制作各种点牌或卡片。使用宾果笔或贴纸来表示“点”或板上的点。尝试按照所示的各种方式排列点(对于三个,在一个板上和另一个板上制作一排三个点,将三个点排列成三角形图案。)尽可能用1-表示数字3点安排。完成后,您应该有大约15个点牌或卡片。由于您需要一遍又一遍地使用这些印​​版,因此不应轻易擦掉或剥离这些圆点。拿起一个或两个盘子,询问它/它们代表的数字,或者有多少个点。这样做很多次,直到答案几乎变为自动。使用点牌作为基本的附加事实,拿起两个盘子并要求总和。使用点板来教导5和10的锚。拿起一个盘子,然后再说5个或10个以上,并经常重复,直到孩子们快速反应。使用点板进行乘法运算。你正在做的事实,拿起一个点牌并让它们乘以4.或者保持4并继续显示不同的牌,直到他们学会如何将所有数字乘以4.每个月引入一个不同的事实。当所有事实都已知时,随机托起2块板,并要求它们相乘2.使用板1次或1次以上或2次或2次以下。拿起一个盘子,说这个数字少于2或这个数字加2.点盘或卡只是帮助学生学习数字守恒,基本加法事实,基本减法事实和乘法的另一种方法。但是,它们确实让学习变得有趣。如果您是老师,您可以每天使用点盘进行钟表工作。学生也可以玩点盘。

新加坡南洋理工数学Assignment代写:基本数学的点板卡

When children learn to count, it often takes the form of rote or counting by memory. To help young learners understand number and quantity, this home made set of dot plates or dot cards will be invaluable and is something that can be used over and over again to help with a variety of number concepts. Depending on the age of the child or children, you can use one or two plates at a time for the following activities. Each activity will have you holding up one or two plates and asking questions. The goal is for the children to recognize the shape of the dots on the plate and when held up, they will recognize that it’s a five or a 9 relatively quickly. You want the children to get past one to one counting of the dots and to recognize the number by the dot arrangement. Think of how you recognize the number on dice, you don’t count the pips but you know when you see a 4 and a 5 that it is 9. This is what you want your children to learn. Using paper plates (not the plastic or styrofoam type as they don’t seem to work as well) or stiff card stock paper use the pattern provided to make a variety of dot plates or cards. Use a bingo dabber or stickers to represent the ‘pips’ or the dots on the plates. Try to arrange the dots in a variety of ways as shown (for a three, make a row of three dots on one plate and on another plate, arrange the three dots into a triangular pattern.) Where possible, represent a number with 1-3 dot arrangements. Upon finishing, you should have approximately 15 dot plates or cards. The dots should not be easily wiped off or peeled off as you will want to use the plates over and over again. Hold up one or two plates and ask what number it/they represent, or how many dots there are. Do this many times until the answers almost become automatic. Use the dot plates for basic addition facts, hold up two plates and ask for the sum. Use the dot plates to teach anchors of 5 and 10. Hold up one plate and say, what’s 5 more or 10 more and repeat often until the children respond quickly. Use the dot plates for multiplication. Which ever fact you’re working on, hold up a dot plate and ask them to multiply it by 4. Or keep 4 up and keep showing a different plate until they learn how to multiply all numbers by 4. Introduce a different fact each month. When all facts are known, hold up 2 plates randomly and ask them to multiply the 2. Use the plates for 1 more than or 1 less than or 2 more than or 2 less than. Hold up a plate and say this number less 2 or this number plus 2. Dot plates or cards are just another way to helps students learn number conservation, basic addition facts, basic subtraction facts and multiplication. However, they do make learning fun. If you are a teacher, you can use the dot plates daily for bell work. Students can also play with the dot plates.
