## Visiting Grandma

Achievement Objectives
GM1-1: Order and compare objects or events by length, area, volume and capacity, weight (mass), turn (angle), temperature, and time by direct comparison and/or counting whole numbers of units.
Student Activity

Ana is going to see her Grandma in 6 days from now.

What is today's date?

What date will she see her Grandma?

Specific Learning Outcomes
Use a calendar to tell days of the week
Devise and use problem solving strategies to explore situations mathematically
Description of Mathematics

This problem applies addition to dates. If there is a big event coming up such as a school trip or an important anniversary, then use this problem in that context.

The extension requires knowledge of both the number of days in the week and the number of days in the current month. Use a date that is correct for the current day/month/year.

Activity

### Problem

Ana is going to see her Grandma in 6 days from now.

What is today's date?

What date will she see her Grandma?

### Teaching Sequence

1. This problem could be introduced in relation to daily news board where the students identified the current day and date.
2. Give each of the students (or pair of students) a copy of the calendar for the current month. Ask them to point to certain dates to reinforce their use of the calendar.
3. Pose the problem.
4. As the students solve the problem focus their thinking on the calendar.
For example:   How many days are there in April?                                                                                                                                                                                                            Show me how you found that out.                                                                                                                                                                                                              How many Mondays are there in April?
5. Share solutions.

#### Extension to the problem

Ana has just returned from spending 8 days with her Grandma. What is the date and day now?

Grandma is coming to stay in 5 weeks from today. When will she arrive?

#### Other contexts for the problem

Excursion in the Easter holidays

#### Solution

The question can be answered by using arithmetic applied to the dates or by using a calendar. For example : adding 6 to 23 gives the answer as the 29th April. Equivalently the students can count on 6 from 23rd April on a calendar to find the same answer.

Extension

Adjust for dates you are using. Have students model counting on 8 full days, leaving and returning on the following day. Connect this to the numbers on the calendar. Model moving into the beginning of the next month if appropriate.

Have students talk about and demonstrate on a calendar how to count on five weeks from today.
