Addition Word Problems Sums Within 20 | Start Unknown |Think Boards & Posters
$5.00
The word problems in this resource focus on addition sums within 20 and are all “Start Unknown” problems. Start Unknown addition problems are problems that require the student to find how many there were to begin with after a number of items have joined them resulting in a known total. These are very hard problems for young students. The problems are presented on Think Boards, great graphic organizers that outline different strategies that may be used to solve the problem.
As a result of using these think boards, your students will be armed with the knowledge and experience of using a variety of strategies and they will start to make their own decisions as to the most appropriate strategy for them to use at any one time.
You will find:
- 5 posters showing the strategies used on the Think Boards for you to print and display in the classroom
- 10 Think Boards – (2 per page) “Start Unknown” addition word problems – numbers to 20
- 4 Think Boards – the number sentence (equation) is provided and students must create the number story
- 2 Assessment Worksheets – each with 5 word problems.
