It is recommended that teachers review activities and read the associated directions and/or lesson plan ideas prior to using them with their students. In some cases, the activities are very open-ended and are best used in conjunction with paper/pencil activities or when students are paired and working on a single computer. If the directions and/or lesson plans are not obvious, a link is provided within the description of the resource.

It is essential that these standards be addressed in contexts that promote problem solving, reasoning, communication, making connections, and designing and analyzing representations.

K.1 Number and Operations and Algebra: Represent, compare, and order whole numbers, and join and separate sets.

Students build, fill, identify, or add items to a ten frame to learn basic number facts.

These four games help develop counting and addition skills. Good resource for ELD learners. This activity does a good job reinforcing ten frame use. Helps students think in chunks of 5.

Students match pictorial number representation with digits, count objects and match with value, and order numerals 1-6.

Site does not give teacher/adult instructions, although "games" are easy to figure out. Easy to manipulate and age appropriate for early kindergarten (pre-kindergarten) skills. Site is great for learning to manipulate the cursor/mouse.

K.1.3

Count forward by ones beginning with any number less than 30; count backward by ones beginning with any number 10 or less.

Students can build, fill, identify, or add items to a ten frame to learn basic number facts.

These four games help develop counting and addition skills. Good resource for ELD learners. This activity does a good job reinforcing ten frame use. Helps students think in chunks of 5.

Students match pictorial number representation with digits, count objects and match with value, and order numerals 1-6.

Site does not give teacher/adult instructions, although "games" are easy to figure out. Easy to manipulate and age appropriate for early kindergarten (pre-kindergarten) skills. Site is great for learning to manipulate the cursor/mouse.

K.1.5

Count objects in a set using one-to-one correspondence and produce sets of given sizes.

Students can build, fill, identify, or add items to a ten frame to learn basic number facts. Activity #2 "Build" supports K.1.5.

These four games help develop counting and addition skills. Good resource for ELD learners. This activity does a good job reinforcing ten frame use. Helps students think in chunks of 5.

K.1.6

Compare and order sets or numerals by using both cardinal and ordinal meanings.

Students order numerals 1-6. Easy to manipulate and age appropriate for early kindergarten (pre-kindergarten) skills. Site is great for learning to manipulate the cursor/mouse.

K.1.7

Model simple joining and separating situations and represent them with objects, pictures, and/or numerals.

Students can build, fill, identify, or add items to a ten frame to learn basic number facts. Activity #4 "Add" supports K.1.7.

These four games help develop counting and addition skills. Good resource for ELD learners. This activity does a good job reinforcing ten frame use. Helps students think in chunks of 5.

Students practice addition and subtraction skills by adding and subtracting train cars to match the number on the rolled die. This activity may be used independently by students as the directions are spoken and modeled.

K.1.8

Choose, combine, and apply effective strategies for solving joining and separating problems.

N/A

K.1.9

Identify, duplicate, and extend simple number patterns and sequential and growing patterns (e.g., patterns made with shapes).

Activities include an interactive figure for creating, comparing, and viewing multiple repetitions of pattern units and illustrates how students can create pattern units of squares, then predict how patterns with different numbers of squares will appear when repeated in a grid and check their predictions.

Identify, name, and describe basic two-dimensional shapes (e.g., square, circle, triangle, rectangle, regular hexagon) presented in a variety of ways (e.g., with different sizes or orientations).

Students use pattern block shapes to create an original quilt patch or one selected from a menu. Tools are available for students to use (spin, flip, eraser, grid) as they build their patches. Teacher needs to supplement site by naming and describing pattern block shapes in instruction to students.

This activity helps develop visual spatial skill as students determine how the shape changes when it is flipped or spun.

Students play a game of concentration matching shapes to their names; names can be played aloud. Selecting the "Geometric Shapes" option supports K.2.1.

K.2.2

Identify, name, and describe basic three-dimensional shapes (e.g., sphere, cube, and cylinder).

N/A

K.2.3

Use basic shapes and spatial reasoning to describe and model objects in their environment, and to construct more complex shapes.

N/A

K.3 Measurement: Compare and order objects by attributes.

K.3.1

Identify the measurable attributes (e.g., length, weight) and non-measurable attributes (e.g., color) of an object.

Students practice sorting blocks by color, shape and size. The check button indicates whether the task has been done correctly.

Teachers should provide guidance before allowing students to work independently or with a partner.

K.3.2

Compare, sort, and order objects according to measurable (e.g., longest to shortest, lightest to heaviest) and non-measurable (e.g., color, texture) attributes.

After a brief introduction, students are given the opportunity to compare the lengths of objects directly and indirectly. There are three levels of difficulty.
