An hour of entertaining mathematics 2018
-Diagnostics of the level of formation of mathematical thinking;
-development of attention;
-increase of children's interest in mathematics;
-bringing self-control skills, confidence in their capabilities.
The game involves 2 teams of 5 people (3rd class). For the victory in each contest the team receives a token. The team that showed the best results with the highest number of tokens becomes the winner of the whole game.
"In order of numbers"
Two teams of 5 people line up in front of the leader (they may be a teacher of mathematics). The host has two different color cards with numbers from 1 to 10. Before the beginning of the game, the presenter mixes cards and one pins each player on his back. No one should know what number is behind him. Everyone can learn this only from his neighbor. At the signal players of each team should be reorganized so that the numbers on their cards were arranged in order. The team that completed this task faster and without errors, wins.
Competition "Merry arithmetic"
Two teams of 5 people line up, each card has a number from 1 to 10 on the chest. The presenter loudly announces: "To 39 add 15" For a moment all the participants consider themselves, and suddenly two people of each team rush headlong to the chairs, standing opposite. Each pair aspires to sit down so that on their cards it is possible to read the sum 54.
12 + 4 = 16 13 + 11 = 24 89 + 1 = 90 25 + 10 = 35 70 + 17 = 87
12 + 24 = 36 15 + 32 = 47 27 + 31 = 58 24 + 5 = 29 10 + 2 = 12
(there are also examples of subtraction)
"Arithmetic Physical Culture"
Players sit in a row and are calculated on 1-10. everyone must remember his number. The head calls a particular number. The summoned person must stand up immediately. Then the head calls two-digit numbers. For example: 17 (get up 1 and 7). When the players get it, the host suggests that they get up not those whom they named, but his neighbors on the left and right, for example: 5 get up (4 and 6). After that, examples are for addition and subtraction. For example: K 3 + 6 = 9 (those who have "9" stand)
Play two teams of 10 people with cards on their chest. Against each team, two chairs are placed at the wall. The leader calls a number - the product of two numbers, for example, 56. Those playing on the chest, whose tablets with multipliers 7 and 8, run out and sit down on the chairs. The token is given to the team that will be able to do it faster, without allowing mistakes. The team that won more tokens wins.
3 * 5 = 15 4 * 9 + 36 8 * 6 = 48 2 * 7 = 14 6 * 9 = 54 7 * 8 = 56 8 * 4 = 32 5 * 6 = 30 9 * 3 = 27
"Who will decide before?"
The game involves two teams of 5 people. Before the teams on the table, they put sheets with arithmetic examples (their complexity depends on the age, but they should be solved quickly and easily.) The examples are the same for teams .At the signal of the presenter, one representative from the team runs to the table, each one selects from his stack any sheet, decides example, writing and putting the sheet back, followed by the second players, then the third, etc. The team that completed the task first, assumes that all the examples are solved correctly.
25 + 56 = 81 52 + 45 = 97 87-24 = 63, etc.
The results are summed up. Rewarding.
