Chocolate histograms

Hi!

Today I want to show you an activity to work with the term of 'statistics' with Lacasitos:



The objective of the activity is to learn the concepts of relative frequency, absolute and work with bar charts through the use of manipulative materials.

The class is divided into four groups of four to six members, the tables are organized so that they can work together and thirty selected Lacasitos are distributed to each group in such a way that they all have 5 reds, 10 white ones, 4 yellow ones, 3 blue ones, 6 green and 2 brown. They are asked to try to fill in the table with the number of Lacasitos among all the members of their team.



They are also asked to group them by color, make rows and try to make a graphic with them and then pass it to the paper in the following way:


Then the teacher will explain the concepts of absolute and relative frequency and ask them to fill in the first two boxes of the table with the appropriate name as they see fit. That is, above the number of Lacasitos, absolute frequency and above no / total, relative frequency. The teacher will show on the digital board different bar graphs taken from real life, with examples and current data such as the immigration rate in the European Union, temperature or rainfall record in the different autonomous communities, use of public transport in different countries , etc.


Materials: Half a kilo of Lacasitos of six different colors

Evaluation:
The teacher will ask questions in order to check that they have understood the concepts of the type: What is the relative frequency of boys / girls in this class?
What is the relative frequency of brown hair in this class?
What is the absolute frequency of courses at this center?
What about the 6th grade primary?
How many players does your favorite soccer team have? What is the relative frequency of foreigners?
 ....
At the time of showing the different bar graphs, you will ask questions to see if you can interpret them.

For this game it is They need 24 chips and two dice. Instructions and objective of the game: Two players must participate in this game; each of which has 12 chips. Each card must be placed in each of the twelve boxes (one card per box). The first player will throw two dice, add the points obtained in the upper faces of the same and will pass to the other side of the river the chip that is located in the box that has the number that has obtained when making the sum. Then the two dice will be thrown by the second player who must repeat the same process. This should continue until o...

Hi! Two posts before, I showed you an activity to work with statistic. Today I want to show you another one to work with this term. In this case, we are going to work with coins. The objective of the activity is to work on the concept of probability, possible cases and favorable cases in a playful, entertaining way and using manipulative auxiliary material as support. The class is divided into groups of four to six depending on the number of coins we have and the number of students in the class and the tables are organized so that they can work together comfortably. Whiteboards, markers and the same number of coins are distributed to all groups. For example: one for € 2, two for € 1, three for € 0.50, four for € 0.20, five for € 0.10, six for € 0.05, seven for € 0.02 and eight for € 0.05. € 0.01. The teacher asks questions and gives them time to play, investigate, test, discuss and reach a conclusion, then rotate the explanations by group, writing the answer on the b...
