Level One > Number and Algebra

AO1: Use a range of counting, grouping, and equal-sharing strategies with whole numbers and fractions.

Children

Resource

Ten in the Bed

The unit uses the poem “Ten in the Bed” as a focus for the students to begin to explore patterns in number.

Resource

Counting on Counting

The purpose of this unit is to explore and develop understanding of cardinality and one-to-one matching, conservation, counting patterns and simple addition and subtraction of sets.

Resource

The Three Pigs

In this unit the students design and construct homes for the three pigs. Each of the homes is made and filled with patterns that we explore.

Resource

Beetle Wheels

In this unit of work we link the development of skip-counting patterns to bars on a relationship graph. We also plot our skip-counting patterns on a hundreds board.

Resource

Ten in the Bed

In this unit students will experience skip counting in twos and fives based on the common nursery rhyme “Ten in the Bed”.

Resource

Make a 100

In this unit the students form collections of a 100 objects. In doing this they examine the relationship between 100 and smaller numbers, specifically 10.

Resource

More Lollies

Solve problems up to 20 using subtraction and addition.

Resource

This activity is to encourage students to skip count to help them find the answer to problems involving equal groups. It is designed to help students make the link between ‘whisper’ counting with body percussion and solving multiplication facts.v

Resource

Up we go

In this unit we work on word problems about climbing up steps and riding in a lift. We learn about different types of problems that can be modelled on number lines. We practice mental calculations with sums to 10 and to 20.

Resource

Money for starters

There are two key intended learning outcomes for this unit. Firstly that students will become familiar with NZ currency and secondly students will be able to identify and compare the values of different units of currency. So, not only will they recognise money, but they will have an understanding of how many 10c coins are equal in value to a 50c coin (for example).

Resource

The Number Partner

This unit uses one of the digital learning objects, the number partner, to support students as they investigate possible pairings for numbers from 10 to 30. It is suitable for students working with Advanced Counting and Early Additive strategies (Stage 4-5 of the Number Framework). It includes problems and questions that can be used by the teacher when working with a group of students on the learning object, and ideas for independent student work.

Resource

Skip it to multiply it

This unit explores early multiplication where students are encouraged to skip count to solve story problems, rather than counting all. For example "John has 3 ponds and there are 2 fish in each pond. How many fish are there altogether?" Students will be encouraged to solve this problem by going 2, 4, 6. "There are 6 fish altogether."

Resource

Gremlins

Model and explain subtraction facts to 10 and then 20.

Devise and use problem solving strategies (act, draw)

Resource

Buttons and Bears

Resource

The Three Cold Kittens

Count groups of two to 6;

Use equipment to model and add sets of twos.

Resource

Pizzas And Things

Count groups of two to 6

Use equipment to model and add sets of twos.

Devise and use problem solving strategies (draw a picture, use equipment, guess and check, be systematic).

Resource

Mrs Parore's Laundry

Use simple problem solving strategies;

Solve a simple problem involving number.

Resource

Lollies!

Solve addition problems with numbers up to 20.

Resource

Points

Add several small numbers.

Devise and use problem solving strategiesto explore situations mathematically. This problem uses guess and check, be systematic, draw a picture, and think.

Resource

You Be The Teacher

Use their mathematical knowledge to invent basic addition and subtraction problems;

Solve other students’s problems.

Devise and use problem solving strategies to explore situations mathematically.

Resource

Well,Well!

Skip count in twos

Investigate and find patterns in addition and subtraction

Devise and use problem solving strategies (act it out, draw a picture)

Resource

Counting Cubes

skip count in 2s, 3s, and 5s

devise and use problem solving strategies (make an organised list)

Resource

Measuring Beads

In this unit we compare the weight of the students’ favourite soft toys directly and then indirectly using beads. Although the technically correct term to use is mass rather than weight we believe that at Level One it is confusing to be "particular" about the difference. As the students will be most familiar with the term weight we believe it is reasonable to use it to describe this week's activities.

Resource

Ways to Add

In this unit students explore different ways to communicate and explain adding numbers within ten. The representations included are number lines, set diagrams, animal strips and tens frames.

Resource

How Many Cubes?

Count a set of objects in the range 1–10.

Resource

Adding and Subtracting with Counters

Solve addition problems to 20 by joining sets and counting all the objects.
