2.1 The student will
a) read, write and identify the place value of each digit in a three-digit numeral, using numeration models;
and
b) round two-digit numbers to the nearest ten.
Activities
1. Rounding - Share the Rounding Numbers poem with the students. The students will complete the
Kidspiration Rounding Numbers template by dragging the stars onto the correct chalkboards. See template
below.
2.2 The student will compare two whole numbers between 0 and 999, using symbols (>,<, or =) and words
(greater than, less than, or equal to).
Activities
2.3 The student will identify the ordinal positions first through twentieth, using an ordered set of objects.
Activities
2.4 The student will identify the part of a set and/or region that represents fractions for one-half, one- third,
one-fourth, one-eighth, and one-tenth and write the corresponding fraction.
Activities
2.5 The student will
a) count forward by twos, fives, and tens to 100, starting at various multiples of 2, 5, or 10 using mental
mathematics, paper and pencil, hundred chart, calculators, and/or concrete objects, as appropriate;
b) count backward by tens from 100;
c) group objects by threes and fours; and
d) recognize odd and even numbers, using objects.
Activities
1. Odd and Even - Discuss odd and even numbers with the students. Using the Odd and Even Kidspiration
template the students will type whether the number is odd or even. When the students have completed this
activity they can make their own odd and even pictures. See template below.
2.6 The student will recall basic addition facts - i.e., sums to 18 or less - and the corresponding subtraction
facts.
Activities
2.7 The student, given two whole numbers whose sum is 99 or less, will
a) estimate the sum, and
b) find the sum, using various methods of calculation (mental computation, concrete materials, and paper
and pencil).
Activities
2.8 The student, given two whole numbers each 99 or less, will
a) estimate the difference; and
b) find the difference, using various methods of calculation (mental computation, concrete materials, and
paper and pencil).
Activities
2.9 The student will create and solve one-step addition and subtraction problems using data from simple
tables, picture graphs, bar graphs, and practical situations.
Activities
1. Create a graph using http://nces.ed.gov/nceskids/createagraph/.
2.10 The student, given a simple addition or subtraction fact, will recognize and describe the related facts
which represent and describe the inverse relationship between addition and subtraction (e.g., 3 + ___ = 7,
___ + 3 = 7, 7 - 3 = ___, and 7 - ___ = 3).
Activities
2.11 The student will
a) count and compare a collection of pennies, nickels, dimes, and quarters whose total value is $2.00 or
less; and
b) identify the correct usage of the cent symbol, dollar symbol ($), and decimal point (.).
Activities
1. Making Change - Read the book Making Money by Abby Jackson. The students will complete the
Kidspiration Counting Money templates and the Kidspiration Making Change template. See templates below.
2. Students can complete the Money Cyberhunt worksheet using the Learning to Use Money website.
2.12 The student will estimate and then use a ruler to make linear measurements to the nearest
centimeter and inch, including the distance around a polygon in order to determine perimeter.
Activities
1. Students can complete activities on this measurement website
http://www.eduplace.com/kids/mw/practice/2/ep2_07.html.
2.13 The student, given grid paper, will estimate and then count the number of square units needed to
cover a given surface in order to determine area.
Activities
2.14 The student will estimate and then count the number of cubes in a rectangular box in order to
determine volume.
Activities
2.15 The student will estimate and then determine weight/mass of familiar objects in pounds and/or
kilograms, using a scale.
Activities
2.16 The student will tell and write time to the quarter hour, using analog and digital clocks.
Activities
1. Use www.abc.net.au/countusin/games/game10.htm to match up time.
2.17 The student will use actual measuring devices to compare metric and U.S. Customary units (cups,
pints, quarts, gallons, and liters) for measuring liquid volume, using the concepts of more, less, and
equivalent.
Activities
2.18 The student will
a) use calendar language appropriately (e.g., months, today, yesterday, next week, last week);
b) determine past and future days of the week; and
c) identify specific dates on a given calendar.
Activities
1. Students can use a Kidspiration calendar template to answer calendar questions. See example below.
2.19 The student will read temperature on a Celsius and/or Fahrenheit thermometer to the nearest 10
degrees.
Activities
2.20 The student will identify, describe, and sort three-dimensional (solid) concrete figures, including a
cube, rectangular solid (prism), square pyramid, sphere, cylinder, and cone, according to the number and
shape of the solid's face, edges, and corners.
Activities
2.21 The student will identify and create figures, symmetric along a line, using various concrete materials.
Activities
2.22 The student will compare and contrast plane and solid geometric shapres (circle/sphere,
square/cube, and rectangle/rectangular solid).
Activities
1. Read Three Pigs, One Wolf, and Seven Magic Shapes by Grace Maccarone to the class. Students can create
tangram pictures on the virtual manipulatives website nlvm.usu.edu/en/nav/vm1_asid_268.html.
2.23 The student will read, construct, and interpret a simple picture and bar graph.
Activities
2.24 The student will record data from experiments, using spinners and colored tiles/cubes, and use the
data to predict which of two events is more likely to occur if the experiment is repeated.
Activities
2.25 The student will identify, create, and extend a wide variety of patterns, using numbers, concrete
objects, and pictures.
Activities
2.26 The student will solve problems by completing a numerical sentence involving the basic facts for
addition and subtraction. Examples include: 3 + ___ = 7, or 9 - ___ = 2. Students will create story problems
using numerical sentences.
