# Measure, compare, add and subtract: lengths (m/cm/mm); mass (kg/g); volume/capacity (l/ml)

New Maths Curriculum (2014): Year 3 objectives.

 Reading Scales - Capacity Word Problems Read the scales on the measuring cylinder and answer word problems involving addition and subtraction. Play against the clock for points.

Measure mass, capacity and temperature. For more measuring resources click here. Balancing Scales g and kg Add weights to either pan until they are balanced. Can be used to teach addition, subtraction, partitioning, and mass, as well as developing an understanding of the equals sign. Choose from grams, whole kilograms or kilograms with either 1 or 2 decimal places. For more addition and subtraction resources click here. For more partitioning resources click here. ITP measuring cylinder October 2012 - I have added a new game in which you read numbered and unnumbered scales on a range of different measuring equipment. Click here to play View full screen in your browser.  This ITP allows you to control two taps that pour a liquid in and out of a measuring cylinder. You can set the scale on the cylinder to a maximum of 50, 100, 200, 500 or 1000 units and the scale interval to 1, 2, 5 or 10 units. You can simply turn the taps on and off and ask questions that involve prediction, addition and subtraction. Using the inlet and outlet controls to set the amount of liquid to pour in and out of the cylinder offers the opportunity for the introduction of multiplication (repeated addition) and division (repeated subtraction) too. A marker can be set to indicate an early quantity. The ITP can be used to explore and consolidate the interpretation and reading of scales, mental calculation strategies and methods of recording. Using different scales can support children’s estimation skills and provides a context for problem solving involving capacity and volume.

ITP measuring scales October 2012 - I have added a new game in which you read numbered and unnumbered scales on a range of different measuring equipment. Click here to play View full screen in your browser.  This ITP allows you to add different masses to or from a scale pan. You can add masses of 1, 2, 5, 10, 50, 100 and 500 units. The pointer or hand shows the total mass. This can be hidden to promote children’s prediction skills. The maximum value of the circular scale can be changed together with the size of the interval. A digital readout can also be hidden or displayed. A red marker can be used to keep a track of previous values and to set target quantities. The ITP can be used to support children’s calculation strategies. Using different scales can support their estimation skills in reading circular scales and solve problems set in the context of mass.

ITP Ruler View full screen in your browser.  This ITP displays an on-screen ruler you can use to measure lines and the sides of shapes. There is a choice of rulers and five screens to use to demonstrate measuring length. You can draw your own lines and shapes or select those that are available on the ITP. The ITP can be used to demonstrate how to use measure using different rulers. The ITP can be used to compare lengths and the perimeters of shapes and to support children’s understanding of scale. You can develop their ability to estimate length against a given scale and use the ruler to check the accuracy and demonstrate what to the nearest half and whole unit means.
