Beginning Processes
With regards to the language model this resource would be used in the concrete materials stage as glasses are a familiar resource, and it’s something that the children can physically touch. To match the parts of liquid, colours or glasses, it’d be used after children have the concept of matching (the objects have to have a common feature). This would be to practise the concept.
To practise a skill it could also be used with the mathematical language. Either having the children answer the correct way. For example when the ½ glass is shown, instead of having the children say “it’s half full/empty”, get them to reply with “one out of two parts” or “half of a whole”. To use this resource in the symbolic mathematical language stage, get children to write down the problem and solve it. E.g. 1/2+1/4= ¾. This resource would be used because it portrays real life scenarios that all children can relate to.
This resource was made by searching “glasses” on the internet. Five appropriate ones were selected because of their shape and less detailed graphics. They were then saved and put into Microsoft Powerpoint. From there a tool that allows lines to be drawn and connected was used. This was done for four separate amounts of liquid, which goes within the ACARA guidelines. Then they were filled with different colours. After that the resource was printed and laminated, followed by being cut up.
The dimensions of the glasses range from 12cm x 7cm to 12cm x 4.5cm.
This resource is used to introduce the skill and concept of matching with fractions, colours and glasses. This demonstrates the skill through matching the same colours, the amount of liquid or the shape of the glasses. From here the children can be asked “how much liquid is in this glass”, “how much more or less liquid do we need for the glass to be empty or full” or “can you match all the glasses that show ¼?” It can be used to introduce this skill or concept as it is using real world and familiar materials in a photo. While later on the same resource can be used to practise recognition of parts of a whole (fractions). From there they can be add or subtract liquid from the glass to get an answer, for example ¾ + ¼ = 1.
