Abstract

Embodiments of the invention disclose a virtual manipulative to facilitate math learning. The virtual manipulative comprises a user interface to progressively form one on more columns to hold partial sums or number decompositions to assist a learner in computing a sum.

Claims

1. A method, comprising:

displaying a list of addends for a learner to add;

providing a first empty column to receive a revised addend list input by the learner, wherein at least some of the addends in the revised addend list are partial sums or decompositions of selected addends from the list of addends;

receiving said revised addend list as input from the learner;

providing a control to add at least one second empty column at the instance of the learner, each second empty column to receive a further revised addend list input by the learner, wherein at least some of the addends in the further revised addend list are partial sums or decompositions of selected addends from the revised addend list that was input last;

receiving each further revised addend list as input by the learner; and

receiving an answer from the learner corresponding to a sum of all addends in the last-added revised addend list.

3. The method of claim 1, further comprising providing a selection tool to allow the learner to select the selected addends.

4. The method of claim 3, wherein the selection tool highlights the selected addends after they have been selected and before the partial sum corresponding to the addends is received.

5. The method of claim 4, further comprising visually indicating the addends associated with a partial sum.

2. The method of claim 2, wherein the first and second empty columns are arranged from left to right.

6. A system, comprising a

a processor;

and

a memory coupled to the processer, the memory storing instructions which when executed by the processor causes the system to perform a method comprising;

displaying a list of addends for a learner to add;

providing a first empty column to receive a revised addend list input by the learner, wherein at least some of the addends in the revised addend list are partial sums or decompositions of selected addends from the list of addends;

receiving said revised addend list as input from the learner;

providing a control to add at least one second empty column at the instance of the learner, each second empty column to receive a further revised addend list input by the learner, wherein at least some of the addends in the further revised addend list are partial sums or decompositions of selected addends from the revised addend list that was input last;

receiving each further revised addend list as input by the learner; and

receiving an answer from the learner corresponding to a sum of all addends in the last-added revised addend list.

7. The system of claim 6, wherein the first and second empty columns are arranged from left to right.

8. The system of claim 6, wherein the method further comprises a selection tool to allow the learner to select the selected addends.

9. The system of claim 8, wherein the selection tool highlights the selected addends after they have been selected and before the partial sum corresponding to the addends is received.

10. The system of claim 6, wherein the method further comprises visually indicating the addends associated with a partial sum.

11. A computer-readable medium having stored thereon a sequence of instructions which when executed on a system causes the system to perform a method, comprising:

displaying a list of addends for a learner to add;

providing a first empty column to receive a revised addend list input by the learner, wherein at least some of the addends in the revised addend list are partial sums or decompositions of selected addends from the list of addends;

receiving said revised addend list as input from the learner;

providing a control to add at least one second empty column at the instance of the learner, each second empty column to receive a further revised addend list input by the learner, wherein at least some of the addends in the further revised addend list are partial sums or decompositions of selected addends from the revised addend list that was input last;

receiving each further revised addend list as input by the learner; and

receiving an answer from the learner corresponding to a sum of all addends in the last-added revised addend list.

12. The computer-readable medium of claim 11, wherein the first and second empty columns are arranged from left to right.

13. The method of claim 11, wherein the method further comprises providing a selection tool to allow the learner to select the selected addends.

14. The computer-readable medium of claim 13, wherein the selection tool highlights the selected addends after they have been selected and before the partial sum corresponding to the addends is received.

15. The computer-readable medium of claim 11, wherein the method further comprises visually indicating the addends associated with a partial sum.
