Large class mathematics activity sand
Design concept:
Sand is one of children's favorite "toys". Its plasticity and fluidity often excite children: they will play games with sand, rice and sugar. And plant a small tree or grass on the beach, dig a hole in the bunker and let the small animals go home ... What kind of toys do they like to play on the beach? Tools are more than their sand and less than theirs, and there are often disputes (children have experience in measuring length and height, but children are inexperienced in measuring sand and rice. ) I designed the "sand" activity to solve the practical problems encountered in the process of playing sand.
Activities, guide children to cooperate, experiment, record collective statistics to compare problems and solve problems, so as to master scientific sediment quantity in the teaching process and give full play to the role of children's operation in data recording. Beach activities will always be a game on the beach. The exploration of the game is combined with the appropriate combination, so that children can explore their existing interests and goals. exist
Objectives of the activity:
1 Stimulate children's interest in exploration and let them master the exploration activities of transporting sand by scientific methods.
2. Guide children in activities: tools of different sizes are all the same pile of sand, and small tools with fewer tools are transported.
3. Cultivate children's ability to find and solve problems.
Activity preparation:
Sand, cups of different sizes, washbasins, recording paper, pencils, etc.
Activity flow:
1, a dialogue that interests children.
Today, we are playing the game of transporting sand. What tools do you need to transport sand?
2. The first delivery of sand and children.
(1) Requirements: two people will transport sand in turn and record the total amount of sand transported.
(2) The statistical table records the amount of sediment carried by each child, and guides the children to observe and find problems. (Why are the quantities different for each two piles of the same sand transported, and the tools used)
(3) Guide children to transport sand in a scientific way: transport as many discussions and demonstrations as possible at a time, and clearly demonstrate the specific operation rules of transporting sand (a cup of tools).
3, children transport sand, verification.
Statistics of sediment discharge of (1)
(2) According to the observed data, it is concluded that a pile of sand is transported smoothly by using the same tools.
Children use different tools to transport sand.
(1) The big tool for children's prediction is just a pile of sand. What will happen to the number of transportation? & ltBR/(2) Children's surgery
(3) Statistical data
(4) By observing the data, children can draw the following conclusions: childbirth; Small cup and small cup line data, the shipment data of this line ......
Teacher's summary: Tools of different sizes, big tools carry the same pile of sand less, but many small tools.
5. Extend the game. What do the children think will happen when transporting sand in a small bowl? Next time, let's go back and try.
