# The Numerate Environment

## Rich Tasks Promote Reasoning and Problem Solving

#### What does this mean?

Not all tasks provide the same opportunities for student thinking and learning (Hiebert & Grouws, 2007), SanGiovanni, 2015). Student learning is greatest in classrooms where the tasks consistently encourage high-level student thinking and reasoning and least in classrooms where the tasks are routinely procedural in nature

(SanGiovanni, 2015).

#### Criteria for Rich Tasks

The folllowing table is from SanGiovanni, 2015.

#### How do I Support This?

##### CONSIDER

#### Rethinking how we have students solve word problems

For Example:

- Ask students to
**compare two problems**with different scenarios but the same mathematical structure. Discuss the differences and similarities between the two, noting that the scenario can be changed while leaving the underlying mathematical structure and calculations unchanged. - Ask students to
**compose word problems**for a given mathematical calculation (e.g., 30 ÷ 5 = 6). Compare the different problems and their solutions, and discuss the different ways in which the underlying mathematical structure is represented in words (e.g. grammar, syntax, vocabulary.) - Give students opportunities to practise mathematizing word problems; ask them to
**rewrite the problem**or or change the mathematical operation required.

- Discuss the
**language used in students’ word problems**and how that language relates to the underlying mathematical task. - Invite students to
**revise a given word problem**to make it more comprehensible or more realistic. For example, given a word problem set in a shopping scenario, students could research current prices and update the problem accordingly. - Ask students to
**compose and solve word problems relating to recent events**in their lives, such as a trip, shopping expedition, or hockey game. It is important that these events be elicited from students. - Invite students to
**engage with problem contexts by extending them in different ways**(e.g, given a problem about a garden design, ask students to create a picture of the garden; given a problem about a school trip, ask students to prepare a short drama scene or write a story about what happened on the trip).

(Examples taken from Barwell, 2011, p. 4; Geiger 2016)

#### Create Low Floor, High Ceiling Tasks

- Creating
**tasks that are challenging yet accessible to all students.**Tasks must feel achievable to students. These tasks are called**Low Floor, High Ceiling tasks**. Everyone in a group can begin and then work at the task at their own level .

#### Using a Range of Strategies

- Requiring
**all students to have a range of strategies and approaches from which to choose**in solving problems, including but not limited to, general methods, standards algorithms, and procedures (SanGiovanni, 2015).

#### Modeling Thinking Strategies

- Providing rich math tasks along with scaffolded instruction,
**explicitly modeling thinking strategies**and encouraging students to self monitor and self question as they work through the tasks (Henningsen & Stein, 1997). - Using
**Number Talks**to develop computational fluency.

#### Integrating Math Planning

**Integrating mathematics into the study of other content areas**or**use other subjects as the context to teach mathematics**(e.g. health and nutrition) in order to help students apply mathematical concepts to everyday life (Carraway et. al, 2015).
