Use money and discuss how the coins represent ones, tenths and hundredths.Use base ten blocks and grids to represents the decimal fractions and decimal numbers.Money is a great way to practice decimals as well. Grids of 10, 1 also allow the students to visualize the decimal numbers and understand equivalence. Using number lines is very important as it allows students to compare decimal numbers. However, students need to understand how grid models work with decimals and fractions.Make sure that your students understand that decimal numbers are just numbers the come between whole numbers (integers) just like fractions and express part of the whole. What do teachers and learners need to know?This technology aspect of the tool was pretty self explanatory and easy to use. I see this being useful for my strategy groups of students who need intervention with addition, subtraction or multiplication with fractions or decimals.6. This could be used as part of your mini-lesson as you introduce the concept or it could be used whole class as they solve problems involving fractions or decimals. How does the technology fit or interact with the social context of learning? Representing Ideas & Thinking - This allows students to see through virtual manipulatives how they solve addition, subtraction and multiplication problems with fractions and decimals.ĥ. However, it is a very simple tech tool so does not have many other uses which could seen as a downfall.Īffordances of Technology for Supporting Learning: It is very easy to use so students could use it to model their thinking and accurately solve their task. I believe the major advantage of this tech tool is that it allows students to visualize how the problem is solved. This tech tool is easy to manipulate so students can customize it to whatever problem they are solving. This helps them visualize how to perform different operations (addition, subtraction, multiplication). ![]() It helps students understand when working with fractions and decimals that they are working with parts of a whole. PS-procedural fluency: The use of manipulatives provided in this tech tool help students visualize their mathematical thinking so they are evaluation the equations accurately.įraction/ Decimal Grid is a virtual manipulative. ![]() PS-conceptual understanding: The use of models help students understand what each fraction or decimal represents and build a stronger understanding of what each operations represents. The use of models helps ensure accuracy in students' computation. NCTM-N&0-compute fluently - compute fluently and make reasonable estimates. NCTM-N&0-understand operations - understand meanings of operations and how they relate to one another NCTM-N&0-understand numbers- understand numbers, ways of representing numbers, relationships among numbers, and number systems The online grid lets you see how fractions and decimals represent parts of a whole. LA-Explore - exploring/investigating mathematical ideas LA-Present - (read or attend to) presentation of new content/ideas This tool could also be used individually by students when solving addition, subtraction or multiplication problems involving decimals and fractions. This visualization would help students create an explanation for these objectives. ![]() This tool allows students to visualize how these operations work when working with fractions and decimals. Students can manipulate how many grids are needed as well, as how many rows and columns.ĭescription of Learning Activity: This tech tool could be used when presenting how to add, subtract, or multiply decimals and fractions. Brief Description of Tech Tool: This tool allows students to use virtual grids to solve addition, subtraction and multiplication problems involving fractions or decimals.
