How much is a hectare? Explain the concept of a hectare and describe its size in simple language. The hectare is a metric drawing unit. Nickname: square meter, square hectare (easy to remember and convert). Symbol: Haha? ; The hectare is the metric unit (international unit) of area. A piece of land with an area of one hectare is 10000 square meters.
Unit conversion: introduce the conversion relationship between one hectare and other commonly used area units, such as how many square meters, acres and acres a hectare equals. 1 cm2 = 100 mm2 =0. 1550 in2; 1 m2 = 10000 m2 = 1. 1960 m2 1 hectare = 15 mu = 10000 m2; 1 mu = 666.67m2; 1 ha =10000m2 = 2.475438+0 1 mu; 1 km2 =100ha = 0.38 1 km2.
Practical application: list some examples in real life, such as farmland, parks, sports fields, etc. In farmland cultivation, an area of one hectare can be used as the basic unit of farmland. Farmers can carry out land planning, crop planting and fertilization according to the area of one hectare, so as to improve the yield and benefit of farmland. In urban planning, parks, green spaces and scenic spots in urban planning often use an area of one hectare.
Exercise: provide some simple exercises for students to calculate and practice in handwritten newspapers to consolidate their understanding of one hectare. Measure the area of land, you can use () as the unit; The square with a side length of () meters has an area of 1 hectare. 1 hectare = () meters. 1 square meter = () square decimeter, 1 square decimeter = () square meter. Fill in the appropriate numbers in the brackets. 7 hectares = () square meters 60000 square meters = () hectares, 9 hectares = () square meters; 30,000 square meters = () hectares.
The purpose and significance of making mathematical handwritten newspaper
By making mathematical manuscripts, students need to sort out and summarize their own mathematical knowledge, which can help students understand and consolidate their knowledge more deeply. Making handwritten newspapers requires students to express their thoughts and opinions in the form of words, charts and pictures, which can cultivate students' expressive ability and creativity. Making handwritten newspapers usually requires students to form a group to cooperate, which can cultivate students' team consciousness and cooperation ability.
By making handwritten newspapers, students can turn boring mathematics knowledge into interesting charts and pictures, which can stimulate students' interest in learning and improve their enthusiasm for learning. Making handwritten newspapers requires students' typesetting design, which can cultivate students' aesthetic ability and artistic accomplishment. By making handwritten newspapers, students need to transform abstract mathematical concepts into concrete images and examples, which can help students better understand and apply mathematical knowledge.
