Title of the research: Using coloured caterpillars to help young learners in writing the correct singular and plural tenses. Aims: - To help young learners to discern correct singular and plural tenses based on the subjects given. - To provide alternatives to pupils in learning to determine the correct tenses. - To teach pupils in writing correct singular and plural tenses by using a more effective and memorable method. Intended grammar items: Singular tenses: a. -s b. -es c. -ies Plural tenses: Maintaining the original form of the verb Background of the research: It is very common among young learners, especially those learning English as a second language, to have a hard time in discerning and determining the correct singular and plural tenses to use. The underlying problem here is that they cannot determine the singularity and the plurality of the preceding subjects. This poses a problem to young learners as they often have a hard time in constructing correct simple sentences. The pandemic worsens this underlying problem and poses a lot of challenges for teachers to explain this abstract concept to young learners. They are usually caught in between really understanding this concept or just making mere guesses, in hope of getting them right by luck. Hence, in tandem with the SEAMEO challenge, I have formulated an original idea to help my young pupils in determining the singular and plural tenses correctly and way more efficiently. The method that I determine to use is using coloured caterpillars to help them to determine which singular tenses or plural tense to use. The colours that I decide to use are red, yellow and green. To further explain this concept, red-coloured caterpillar will be utilised to help my pupils to determine whether to add -s at the verb based on the subjects given while yellowcoloured caterpillars will be used to help my pupils to determine whether to add -es at the verb based on the subjects given. Last but not least, green-coloured caterpillars will be used to help my pupils to determine whether to add -ies at the verb based on the subjects given. A pre-test instrument was given to my pupils in order to determine their level before the research. Explanations and hands-on activities were also given and conducted after the pre-test. Pupils were given extensive practices before the post-test instruments were distributed to them.
