6 resources for teachers, students, and families to support instruction in the classroom and at home. Take a product tour of a Math for children 5 years print Mifflin program. Mathematics is commonly called Math in the US and Maths in the UK. MP1 Make sense of problems and persevere in solving them.
Mathematically proficient students start by explaining to themselves the meaning of a problem and looking for entry points to its solution. They analyze givens, constraints, relationships, and goals. Mathematically proficient students make sense of quantities and their relationships in problem situations. MP3 Construct viable arguments and critique the reasoning of others. Mathematically proficient students understand and use stated assumptions, definitions, and previously established results in constructing arguments. They make conjectures and build a logical progression of statements to explore the truth of their conjectures. Mathematically proficient students can apply the mathematics they know to solve problems arising in everyday life, society, and the workplace.
In early grades, this might be as simple as writing an addition equation to describe a situation. Mathematically proficient students consider the available tools when solving a mathematical problem. These tools might include pencil and paper, concrete models, a ruler, a protractor, a calculator, a spreadsheet, a computer algebra system, a statistical package, or dynamic geometry software. Mathematically proficient students try to communicate precisely to others. They try to use clear definitions in discussion with others and in their own reasoning. They state the meaning of the symbols they choose, including using the equal sign consistently and appropriately.
MP7 Look for and make use of structure. Mathematically proficient students look closely to discern a pattern or structure. Young students, for example, might notice that three and seven more is the same amount as seven and three more, or they may sort a collection of shapes according to how many sides the shapes have. MP8 Look for and express regularity in repeated reasoning. Mathematically proficient students notice if calculations are repeated, and look both for general methods and for shortcuts. Upper elementary students might notice when dividing 25 by 11 that they are repeating the same calculations over and over again, and conclude they have a repeating decimal. Connecting the Standards for Mathematical Practice to the Standards for Mathematical Content The Standards for Mathematical Practice describe ways in which developing student practitioners of the discipline of mathematics increasingly ought to engage with the subject matter as they grow in mathematical maturity and expertise throughout the elementary, middle and high school years.
The Standards for Mathematical Content are a balanced combination of procedure and understanding. Expectations that begin with the word “understand” are often especially good opportunities to connect the practices to the content. Students who lack understanding of a topic may rely on procedures too heavily. In this respect, those content standards which set an expectation of understanding are potential “points of intersection” between the Standards for Mathematical Content and the Standards for Mathematical Practice.

American businesswoman Ruth Handler is credited with the creation of the doll using a German doll called Bild Lilli as her inspiration. Barbie is the figurehead of a brand of Mattel dolls and accessories, including other family members and collectible dolls. Barbie has been an important part of the toy fashion doll market for over fifty years, and has been the subject of numerous controversies and lawsuits, often involving parodies of the doll and her lifestyle. Mattel has sold over a billion Barbie dolls, making it the company’s largest and most profitable line.
However, sales have declined sharply since 2014. This section needs additional citations for verification. The first Barbie doll was introduced in both blonde and brunette in March 1959. Ruth Handler watched her daughter Barbara play with paper dolls, and noticed that she often enjoyed giving them adult roles. At the time, most children’s toy dolls were representations of infants. During a trip to Europe in 1956 with her children Barbara and Kenneth, Ruth Handler came across a German toy doll called Bild Lilli. The adult-figured doll was exactly what Handler had in mind, so she purchased three of them.
She gave one to her daughter and took the others back to Mattel. The doll made its debut at the American International Toy Fair in New York on March 9, 1959. The first Barbie doll wore a black and white zebra striped swimsuit and signature topknot ponytail, and was available as either a blonde or brunette. The doll was marketed as a “Teen-age Fashion Model,” with her clothes created by Mattel fashion designer Charlotte Johnson. Louis Marx and Company sued Mattel in March 1961.
Hausser’s patent for Bild-Lilli’s hip joint, and also claimed that Barbie was “a direct take-off and copy” of Bild-Lilli. The company additionally claimed that Mattel “falsely and misleadingly represented itself as having originated the design”. Ruth Handler believed that it was important for Barbie to have an adult appearance, and early market research showed that some parents were unhappy about the doll’s chest, which had distinct breasts. Barbie’s appearance has been changed many times, most notably in 1971 when the doll’s eyes were adjusted to look forwards rather than having the demure sideways glance of the original model. Barbie was one of the first toys to have a marketing strategy based extensively on television advertising, which has been copied widely by other toys.
