3rd grade math worksheets
3rd grade math worksheets, maths worksheets – The critical areas studied as per the Common Core Standards in the USA for 3rd grade math build on the previous standards set. Multiplication and division are taught and strategies are developed for numbers within 100. Multiplication is finding an unknown product. Division is finding an unknown factor. Equal sized, but unknown groups are created through division. Products are created through duplicating multiple groups in multiplication. Students develop the understanding of fractions with the numerator 1. Students are also taught that fractions are relative to the size of their container, example 1/2 of a small bucket might be smaller than 1/3 of a larger bucket. However 1/3 of a ribbon is more than 1/5 of the same ribbon.
The Common Core Standards in the USA also examine the development of the structure of rectangular arrays and area. They also analyze and describe two dimensional shapes. Rectangular arrays can be divided into equal sized columns and equal sized rows through common measurement. Students connect area to multiplication and justify the use of multiplication to determine the area of a rectangle. Students compare the properties of two dimensional shapes. They connect the work with fractions to their work with geometric shapes. For example, they determine half of a geometric shape compared to one third of it.
