What is perimeter and what units do we use to measure it? Perimeter is the distance around the outside of a shape. Here, we will measure length by using metric units (centimeters, meters). What is area and what units do we use to measure it? Area is the size a surface takes up measured in square units. It can be determined using a grid or a formula. (Credits: A Maths Dictionary for Kids) The video below explains on how to get the perimeter and area of a regular shape (a rectangle and a square). Credits: Khan Academy What are interior angles and how do we measure them? How do mathematicians figure out interior angles of a triangle? A triangle is a polygon with three sides and three angles. The total of the angles in any triangle is 180 degrees. These are the types of triangles and its interior angles: 1. Acute triangles - An acute triangle has three angles; each angle measures less than 90 degrees. 2. Right Triangle - A right triangle has one right angle of 90 degrees. 3. Obtuse Triangle - An obtuse triangle has one angle that measures over 90 degrees. 4. Equilateral triangle: a triangle that has three equal sides and three equal angles. 5. Isosceles triangle: a triangle that has two equal sides and two equal angles. 6. Scalene triangle: a triangle that has no equal sides and no equal angles. The photos above are the types of triangles and how I learned about them. I also learned that triangles can be classified by measuring their angles and by measuring their sides. Here is a video about the types of triangles that supported my learning. (Credits: Don'tMemorise.com)

What is TEMPERATURE? Temperature is how hot or cold a place or an object is. When we say, "It is freezing in here!", we are actually referring to the very cold temperature of the room/area. Knowing the temperature of a thing or place is important. The basic units for measuring temperature are the following: Celsius (°C) or Centigrade and Fahrenheit (°F) . These two are the common units, but for scientists, they use Kelvin (K). Celsius is equivalent to 32 degrees Fahrenheit. What are the TOOLS AND MEASUREMENT OF TEMPERATURE? We can use a thermometer to get the temperature. With this tool, we can measure our body temperature. It will tell us if our body is within or beyond the normal body temperature which is 36 °C. If it is too high, that means we have a fever or something is wrong with our body. Here is a photo of my body temperature which is 36 °C.

Here is an example of a cup of liquid that is equivalent to 200 milliliter. Does weight and mass help us? When I was learning how to measure weight and mass, at first, I use a weighing scale. This tool if used properly we will have an accurate measurement. An example is when baking cookies, first is to measure the required amount of ingredients. If this is done precisely, the taste will come out delicious. But if not done properly, the baked goods will definitely not taste good. Below is a YouTube video about the importance of measurements and how it helped me understand it well. #Maths#LearnerProfile#Measurement Now, here is my video of conversion of units in YouTube. In terms of measuring length, especially when I am measuring small objects a tool that I use is a ruler. The length of small objects is usually not more than 30.48 centimeters and using ruler is the most practical one. Below is my video about conversion of centimeters to meters. #Maths #Learner Profile #length #conversion
One thing I learned about the way I think in Math especially about the topic in measurements is that it matters in life. I realized this because we use these measurements in everything that we do, from length, volume and temperature. An example is when someone asks you how far a place could be, I can easily understand and answer what the person is asking me about like telling an estimation of kilometers.
Another example is when I am buying clothes, I should know my measurements or my size like buying t-shirts or pants, so that when I wear it will make me feel comfortable. #math#learner profile |
