|
- Lead students through discussion of attributes of circle,
square, rhombus, triangle, rectangle, parallelogram, trapezoid, hexagon. - Closed, sides, angles. Relate to Pattern Blocks.
|
Use Pattern Blocks Activities -
|
Write journal entry comparing any 2 polygons. | - Independently investigate home/school types of triangles or
quadrilaterals. - Prepare chart for classroom reference. |

|
| Use tangrams, geoboards, and pattern blocks to demonstrate knowledge of geometric shapes. | - Read Grandfather Tang's Story by Tompert. - Demonstrate manipulation of tangrams. |
Manipulate tangrams to create shapes named in story. Translate to grid or dotted paper, label and identify shapes. | Create a design with pattern blocks and give it a value as in
What's It Worth? (p. 19) or given a value, create a symmetrical design reflecting that
value.

|
| Construct geometric shapes using
position vocabulary.
|
Introduce Do As I Say game with pattern blocks. | Work in pairs. Leader creates design in pattern blocks hidden
from partner. Gives oral directions on placement of blocks to copy shape. Once directions
are complete, barrier is removed. Designs compared.
|
Do As I Say, only write directions using shape and position
vocabulary. Good center activity to be shared with classmates.
|
- Pattern Blocks. - Sight dividers (could be file folders, books, etc.) |

| Demonstrate slides, flips, turns of geometric shapes. | Direct students to draw themselves on 3x5 card front and back
sides. Repeat on second card. Write names on cards.
|
Work in small groups and follow teacher's direction showing a slide, flip, turns (4 directions) and then combination. | Relate slides, slips, turns to Pattern Blocks or Cuisenaire Rods. Illustrate on graph or dotted paper. | - Index cards (2 per student). - NCTM Addenda, Gr. 2 - Pattern Blocks. - Cuisenaire Rods. - Graph or dotted paper. |

| List and order the days, months,
seasons, years.
|
Read All In A Day (Anno) or Very Hungry Caterpillar (Carle); ask students to identify math ideas in book. | With partner and then independently, sequence word cards and
number lists of words asking them to sequence either days of week, months, seasons, years.
|
- Read The Day Monday Ran Away by Heit. - Design a calendar that would show what we could have if Monday ran away.
|
- All In A Day by Anno. - Very Hungry Caterpillar by Carle. - The Day Monday Ran Away by Heit. - Teacher-made activity cards.

| Tell time to the nearest 5 minute
interval.
|
Model reading Judy Play Clock.. Students identify time. Teacher gives time. Students model on individual clocks. Relate to digital. | Working with partner or independently, draw hands for targeted times on clockfaces or write time shown on clockfaces. | Design a clock that can show all 24 hours in a day. | - Judy Play Clock. - Small student clocks with moveable hands. - Clock face stamp pad.

time pieces.
|
Prepare cards for Match Game, showing given time in both analog and digital time. | Play Match Game independently or with partners. Name times as card is turned over. Partner checks. | Accurate identification of time shown.
|

| Count, and value a collection of coins:
half dollar, quarter, dime, penny.
|
Set parameters and goals for small group work. Try to find as
many difference combinations of half dollars, nickels, dimes, quarters as possible to make
$1.
|
- Using play money, will find and record different
combinations in small groups. - Results are shared/compared. |
With partner, play Money Exchange Game:Each player
begins with $1.00 bill. At each turn they roll the dice and put the amount they roll into
the bank, exchanging higher denominations for lower as needed. First player with less than
15 cents wins.
|
- Play money. - Coins - all. |

| Identify and value paper currency: one, five, ten. | Set parameters and goals for activity, Spinning & Winning. | Take turns spinning spinner in small group game. Each spin
earns dollars. Goal is to be first to reach $100. status. Bills are exchanged for higher
values when possible.
|
With partner play Money Exchange Game:Each player begins with $100 bill. At each turn students roll the dice and put the amount they roll into the bank, exchanging higher denominations for lower as needed. First player with less than $15 wins. | Play money bills - $1, $5, $10, $20, $50, $100. | ||

| Demonstrate use of temperature scales.
(Celsius and Fahrenheit.)
|
- Discuss 2 ways to measure temperature. - Review vocabulary: temperature, thermometer, Celsius, Fahrenheit. - After activity, share tables of approximate temperatures and through guided discovery make comparisons of 2 scales.
|
Record temperature(s), C and F, on teacher-prepared worksheet. Compare. | Calculate changes in daily high and low temperatures from forecast. Record and graph for a week or month. | - Everyday Mathematics Journal I, p. 40. - Everyday Mathematics, Gr. 2, Teacher's Manual, p. 96. |
