Chaos Created has been busy creating six new activities and games for i-board’s new unit, Simple Addition and Subtraction.
From the TES blog:
These lessons and resources go back to basics with very simple counting on and counting back exercises. Some of the lessons use little story contexts to show the meaning of addition and subtraction in terms of adding or taking away from a group of objects. Others use dice in simple games, for example moving a counter up and down a number line. Finally, this unit makes use of some of our popular skills games from the Skill builders section of the website – fun practice games for use in the computer suite, in the classroom or at home.
Chaos Created developed the following games and activities…
Pupils develop their understanding of number and addition by considering the idea of “more than” a starting amount, e.g. 2 more than 4. This is presented in a “story” context and is then followed up with practice, using dice to set problems.
Pupils return to a real life context to cement their understanding and skills. They use an interactive tool that generates basic ‘addition stories’, with simple animations to show the act of adding more objects to a starting number.
Pupils carry on practising counting back, using an abacus as a visual support. Games are then used to provide a question bank of appropriately levelled questions for pupils to cement their skills.
Drop a Number
Pupils continue with the concept of “counting on”, using an interactive number line to support their understanding of mental addition. They learn to put the biggest number first and why. Games are used to provide a question bank of appropriately levelled questions for pupils to cement their skills.
Similar to lesson 3, but practising subtraction rather than addition, pupils return to a real life context to cement their understanding and skills. They use an interactive tool that generates basic ‘subtraction stories’, with simple animations to show the act of taking objects from a starting number.
Addition and Subtraction Stories
This final lesson brings together the two operations in a Maths Story context. Pupils tell a longer story that includes both “arriving” (addition) and “leaving” (subtraction). This lesson can be carried out in the computer suite or using props/pictures.
