Think Boards are a wonderful device for helping students solve word problems. The student is prompted to use five different strategies to help solve the word problem. The strategies used are: ‘Draw a Picture’, ‘Use a Number Line’, ‘Use a Ten Frame’, ‘Write a Number Sentence’ and ‘Part Part Whole’. The word problems in these resources deal with subtraction sums to twenty. This bundle brings together four types of word problems: Result Unknown, Change Unknown, Start Unknown and Compare. 


There are four resources in this bundle:


In each resource you will find:

  • 5 posters showing the strategies used on the Think Boards
  • 10 Think Boards with sums to 20 (2 to a page)
  • 4 Think boards - the number sentence (equation) is provided and students must create the number story (2 to a page)
  • 2 Assessment Worksheets – each with 5 word problems


That makes a total of 40 word problems and 8 assessment worksheets (another 40 problems). Please check the previews of the individual resources if you need further information.
