Carroll Diagrams – Odd and Even

We’ve just launched Carroll Diagrams – Odd and Even which is an interactive game designed for 6 to 9 year olds. Not only is it a useful resource to help in the understanding Carroll Diagrams but it can also reinforce the concepts of odd and even numbers, more or less than a given number and also place value.

The resource has four levels, each of which requires users to sort by two criteria. The first two levels involve Odd and Even numbers and more or less than a number up to 10 or 99 respectively. There is an excellent level of challenge as the criteria vary from game to game. The resource also works well on interactive whiteboards for class demonstrations and on desktop and tablet devices.

Level 1
Level 1 – Odd and Even and Up to 10
Level 2 – Odd and Even and Up to 99

The next two levels also involve odd and even numbers but the second criteria requires a knowledge of place value, as users need to identify ones, tens and hundreds values.

Level 3 – Odd and Even and Tens or Ones Up to 99
Carroll Diagrams - Odd and Even Level 4
Level 4 – Odd and Even and Hundreds, Tens or Ones Up to 999

New Subtraction Game Launched

We’ve just launched  Subtraction to 10 another free maths game for children aged 5 or 6. Each calculation features a subtraction within 10, along with a pictorial representation of the start number. Children can then select the appropriate multiple-choice answer.

The game works on desktop and mobile devices and is also useful in a class situation on an interactive whiteboard for those children who are just getting to grips with the idea of subtraction. As each calculation is solved the remaining animals move to a number line and those animals which have been subtracted are crossed out. This visual representation of the subtraction process can help to reinforce the concept.

Take a look now at Subtraction to 10.

Yet Another New Addition Game Launched

Robot Addition is a drag and drop multiple choice game aimed at 5 to 7 year olds. Each game mode has the option of displaying a number line to support children who are just getting to grips with the concept of addition.

The game can be replayed many times as the questions are randomly presented and like all Topmarks’ games it is playable on both desktop and mobile devices.
